▼ A spectrally integrated response method is proposed for analyzing transmission data from nanohole array sensors. This method increases the sensitivity by reducing noise and taking more information from the spectrum for bulk and
surface sensing. Results from both real experiments and idealized simulations are presented. Comparison with two other methods- peak transmission wavelength shift and a normalized difference integrated response method are shown. This method shows improved sensing performance which can be exploited in future.
Further improvement in sensing using nanohole arrays is explored by improving the instrumentation of the sensor system. Design parameters of the nanohole arrays for transmission at two different operating wavelengths were examined by using finite difference time domain simulations. Focused ion beam milling was used to fabricate chosen arrays. A microfluidic chip with the embedded nanohole array sensor was used to introduce different solutions for bulk chemical sensing. Intensity measurements were taken with a high speed CMOS camera. Sensing results using this system with possible improvements shows promise for future sensing applications.

▼ Silicon-On-Insulator (SOI) waveguides have attracted great attention for their ability to confine light in a small region. However, one of the main drawbacks of SOI waveguides is their strong polarization dependence. To overcome this issue, variety types of silicon-based polarization rotators have been proposed with long device lengths to achieve sufficient extinction ratios and low insertion losses.
We first utilize the
surface plasmon polariton (SPP) effect to design an ultra-compact polarization rotator consisting of a SOI waveguide covered by a linearly tapered aluminum with a silica gap. The numerical results from a three-dimensional finite element method (3-D FEM) show that the extinction ratio can be enhanced by increasing the device length and reducing the gap. We can obtain a 5.2-μm long polarization rotator with 20.76-dB extinction ration and 2.9-dB loss for TMâTE conversion, and 5-μm long device length with 17.36-dB extinction ration and 2.7-dB insertion loss for TEâTM conversion.
We have also proposed a tilt-metal-grating polarization rotator to achieve TEâTM conversion with high extinction ratio. The polarization conversion efficiency is in proportional to the increased metal thickness and decreased silica gap. Finally, we can obtain a 2.2-μm long polarization rotator with 20.84-dB extinction ration and 3.3-dB insertion loss by optimizing the performance of the rotator.

▼ Our primary goal of this study was to obtain a better
understanding for the carbohydrates binding interactions with human
intelectin (hIntL). Studying the binding specificity of hIntL could
help in discovering its natural substrate and might give us a clue
about its role in the innate immune response as well as its
pathophysiological action in various diseases. In this project,
recombinant expression of intelectins was successfully done using
HeLa cells and H5V cells. Yeast (Pachia pastoris) did not proove to
be a promising expression system for hIntL. Using chemical
synthesis, compounds (3.1–3.9) were obtained to be screened as
ligands for hIntL. Herein, we used surface plasmon resonance (SPR)
as our analytical tool to study hIntL binding specificity towards
various synthesized Galf-containing oligosaccharides. Staudinger
ligation chemistry as well as amine coupling were used to
immobilize the carbohydrate epitopes to the SPR biosensor surface.
Both hIntL-1 and hIntL-2 were screened against the derivatized
surface.

▼ Metal nanostructures, with their extraordinary optical properties, have attracted great attention in recent years. Subwavelength-scaled metal elements, without involving array effects, have the unique ability to confine or route light at the nano-scale. In this thesis, we provide three topics relating to the manipulation of light using metal nanostructures. We first present a theory to solve the end-face reflection of a subwavelength metal stripe, which is beneficial to the design of optical resonator antennas. Subsequently, we take the advantage of the destructive interference among triple nano-slits to sharpen the focus beam in the near-field at near-infrared wavelengths, which is of interest to the study of near-field optical phase imaging and lithography. Lastly, we demonstrate a rectangular subwavelength aperture quad to convert linearly polarized radiation to a radially polarized beam, which is useful to create a deep-subwavelength focus and for optical trapping.

▼ The sensing applications based on surface plasmon resonance (SPR) have been developed rapidly in recent decades. Much attention has been paid for its real time sensing and label-free detection ability. A commercial success of the application on SPR technique is the BiacoreTM SPR systems developed by General Electric (GE) Heathcare. It has been widely used in hospitals and research institutes in various fields from biomedical/chemical reaction detection to the environment monitoring and food safety controlling. However, this prism-based SPR sensing system suffers from its bulk size design, moderate sensitivity and high cost. Further, the invention of optical fibre accelerated the development of SPR sensors, named as fibre optical plasmon sensor (FOPS) by utilizing the conventional optical fibre. It has been proven to be a potentially promising tool for the realisation of small-size sensor with excellent sensing performance and the capability of remote sensing. The FOPS has a significant importance on the development of SPR sensors in various ways. Later on, the emergence of photonic crystal fibre (PCF)with FOPS has opened up a new era of sensing technological innovations. The PCF based FOPS is now becoming a promising optical detection technique for studying label-free bio-molecular interactions in real time. In this thesis, the use of novel PCFs as a new class of optical fibre together with the SPR phenomenon for sensing application is presented and investigated in detail. By manipulating the structural parameters, the PCFSPR sensor can be optimized to achieve higher sensitivity, larger sensing range for better sensing performance and easy-fabrication. Additionally, efforts have been made to investigate the influence of the sub-peak for higher order SPR on the sensing performance. Moreover, a multi-sensing scheme by utilizing metallic nanowires in PCF may provide a new method for fast sensing. The key original contributions of this thesis include: 1. Modified D-shaped PQF-SPR Bio-sensor with Trapezoid Shaped Analyte Channel for High Refractive Index Liquid Analytes with Adjustable Liquid Height. To overcome those two disadvantages - low sensitivity and fabrication difficulty and to extend the sensing range, a six-fold trapezoidal channel (TC) PQF SPR bio-sensor for liquid bio-analyte sensing is demonstrated to investigate how the liquid height in the TC influences the sensing performance. The structure optimization of such sensor is presented for better sensitivity, sensing range and stability. The effective refractive indices and loss spectra peak differences acquired from the simulations of the designed TC-PQF sensor for a range of wavelengths have been solved and calculated thoroughly to evaluate its sensing performance. According to the numerical results, it shows a good sensitivity for the analyte RI ranges of 1.40 to 1.58 which is broad enough to cover most of the bio-samples. Besides, the result also proves that it is possible to control the sensor's detection range by adjusting the liquid analyte's…

▼ In recent years, the
Surface Plasmon Polariton effect has played an important role for entering the Nano-world. When the metallic materials reach the nanometer level, many special characteristics show up. As the progress of advanced technology development, the equipments which can be operated in nano grade level are more stabilized. Many special
surface Plasmonic properties have been discovered through the measurements. This research is to focus on using the
Surface Plasmon coupling to excite colloidal quantum dots and observing the emissive behavior of quantum dots. The experiments of changing the distance between the quantum dots and the metal film were performed. The blinking effect disappeared when the quantum dots are very close to the metal film. It showed that some other mechanism is competing with Auger recombination in the quantum dots. The lifetime modification and emission intensity were measured when one quantum dot was placed near a silver cube. The coupling between the
surface Plasmon polariton and the quantum dot was discussed.

▼ We present a theoretical model and experimental results for a Sagnac ring interferometer resonantly enhanced via
surface plasmon resonance (SPR). One defining characteristic of a resonance is the π change in phase that occurs across the resonance. For a narrow resonance, this results in a steep phase profile which proves advantageous when utilized within a phase-based detection scheme, providing a resonant enhancement that has the potential to greatly improve the sensitivity of Sagnac interferometers. Furthermore,
surface plasmon resonance serves as the mechanism underlying
surface plasmon sensing, one of the more commonly used techniques for detection and characterization of a variety of interfacial events. This method relies on the excitation of
surface bound electromagnetic waves, known as
surface plasmon polaritons (SPPs), which propagate along the interface of a metal and dielectric and exhibit a field profile that decays exponentially into both media. Excitation of SPPs within an interferometric environment provides an avenue for investigation into the potential benefits of this resonant enhancement. In addition, it carries the capacity for insight into applications of SPR sensors using interferometric techniques, some of which may be inaccessible to intensity based detection schemes.
We begin this dissertation by providing necessary background information, such as the interference equations describing the interferometer outputs and the SPP dispersion relation. We then detail the features of SPR and explore modifications to the resonance shape by variation of the system parameters. We fabricate and characterize thin silver films, suitable for supporting SPPs, to be used in sensing experiments. We design a theoretical model to compute the response of the resonantly enhanced interferometer to various perturbations and calculate the corresponding sensitivities. Finally, we construct a resonantly enhanced interferometer in the laboratory, analyze the optical data collected from both interferometer output ports, and comment on the promise of this and similar devices moving forward.

▼ This thesis details the fabrication of three different plasmon-polariton based devices: a plasmon-polariton Bragg grating (PPBG) biosensor, an intensity modulator incorporating grating couplers, and optically separated electrical contact, and finally an array of nanoholes in an ultrasmooth Au film. The biosensor involves a 35 nm Au stripe, lithographically stepped in width to produce a Bragg reflector. The waveguide is embedded in symmetric, Cytop claddings 8 µm thick. Channels are etched into the top cladding, exposing the waveguides and allowing for the integration of fluidics. The modulator involves a 20 nm Au pad, overlaid with 80 nm Au diffraction gratings, supported by an ultrathin (~3 nm) SiO2 insulator, on a p-doped Silicon wafer backed by an Al Ohmic contact. Electrical contact pads are separated from the waveguide by a thick dielectric (700 nm PMMA), and 2.5 µm vias in-filled with Au allow for electrical connection between the contact pads and waveguides. The nanohole array is machined by focused ion beam into an ultrasmooth Au film revealed by template stripping. The Au film is stacked on a thick film of Cytop between ~5 µm thick.

▼ Plasmon based field effect transistors (FET) can be used to convert energy induced by incident optical radiation to electrical energy. Plasmonic FETs can efficiently detect incident light and amplify it by coupling to resonant plasmonic modes thus improving selectivity and signal to noise ratio. The spectral responses can be tailored both through optimization of nanostructure geometry as well as constitutive materials. In this paper, we studied various plasmonic nanostructures using gold for a wideband spectral response from visible to near IR. We show using empirical data and simulation results that detection loss exponentially increases as the volume of metal nanostructure increases and also a limited spectral response is possible using gold nanostructures in a
plasmon to electric conversion device. Finally, we demonstrate a
plasmon field effect transistor that offers a broadband spectral response from visible to telecommunication wavelengths.

▼ Collective oscillation of conduction electrons in metallic nanoparticles known as localized
surface plasmon resonance has been studied for nano-optics applications. The excitation of localized
surface plasmons on nano-structured metal material leads to strong light scattering and absorption. Since the localized
surface plasmon resonance is strongly dependent on the shape, size, size distribution, and dielectric property of surrounding environment of nano-structured metal, the dependence can be applied in wide applications. However, the direct and non-destructed observation of nano-structured metal is required to the development of nano-technology, we proposed a real time optical observation due to the optical respons of metal nano-particles system. Furthermore, we proposed a fast and simple method to fabricate a high order metal nano-particles array and used liquid crystal material to directly modulate the
surface plasmon effect on the metal nanoparticles.
The purpose of this work is to study the
surface plasmon effect excited on metal nanoparticles. These works are described as follows:
A. The topic of the first work is âReal time absorbance spectra due to optical dynamics of silver nano-particles filmâ, we report the real time absorbance spectra due to optical dynamics of silver nano-particles film under a heating treatment from 28 to 300 â. A 7nm-thicked sliver film was thermally deposited on an indium tin oxide glass substrate. In the process of heating, the real time absorbance spectra of silver nano-particles film were measured by an optical spectrometer. It was noted that the absorbance spectra of the film varied with the heat-treating temperature and time. The peak position in the spectra curve shifted to shorter wavelength below the temperature of 250 â, then shifted to red band due to higher temperature treatment. With the comparison of scanning electron micrograph analysis, the real time absorbance spectra exhibited a particular optical property confirmed by the dynamic dark-field optical microscopy system. The real-time absorbance spectra and dark-field micrographs analyses lead to a direct and non-destructed observation of growing evolution of metal nano-particles.
B. The topic of the second work is âLaser pulse induced gold nanoparticles gratingâ. We report the results of our experimental investigation of laser induced gold nano-particle gratings and their optical diffraction properties. A single shot of a pair of Nd-YAG laser pulses of the same polarization is directed toward a thin gold film of thickness 6 nm on a substrate of polymethyl methacrylate (PMMA). As a result of the laser illumination, the thin gold film is fragmented into an array of nano-particles. Using scanning electron and dark-field optical micrographs, we discovered that the morphology of the gold nanoparticles grating is dependent on the fluence of laser pulse. The spectrum of first order diffraction shows a spectral dependence, possibly due to the presence of the nano-particles of various sizes. The ablation of thin films of…

▼ The birefringence of one-dimension PMMA
surface gratings on a gold film substrate is investigated. The grating served as a coupler to facilitate the incoming light coupled to
surface plasmon wave (SPW) which possesses high propagation wave vector. Since
surface plasmon waves(SPWs) have a special dispersion relation, the birefringence Îneff (Îneff =nx-ny, where grating k-vector is along x axis) of this structure is relatively large and can be changed from positive to negative by changing the operation wavelength.
The obtained the four Stokes parameters at 515nm and 633nm are marked on the Poincare sphere. Îneff is
2Ï/7 and -Ï/8 at 515nm and 633nm respectively. Further, by
changing the form factor of PMMA gratings, we found that the maximum Îneff occurred when PMMA stripe width : air gap=1:1.

▼ Metallic nanoparticles due to
surface plasmon effects are used to fabricate devices with particular electro-optic properties, so that, they have been widely studied in many fields. With progressive developments of interesting phenomena and applications, metallic nanoparticles have become an important role in different kinds of the studies. One interesting application is the
surface enhanced Raman scattering associated with metallic nanoparticles. It is worthy to investigate the relationship between the
surface plasmon effects of metallic nanoparticles and the enhancement mechanism of the Raman scattering. Besides, the shape effects of metallic nanoparticles in an array are interesting for a combination with optical circuits. On the basis of these properties of metallic nanoparticles, two studies will be introduced in this dissertation:
First, the intensity of
surface-enhanced Raman scattering (SERS) light of crystal violet (CV) molecules are probed as the molecules adsorbs on silver nanoparticles with SiO2 coating. We find that the intensity of the SERS light from CV molecules varies with the thickness of the SiO2 coating. Hence, this experiment investigates the enhancement mechanism of
surface enhanced Raman scattering by modulating the thickness of the SiO2 coating. In addition, the SiO2 coating can work as a preventer to remain the activity of the silver nanoparticles. This makes the silver nanoparticles with SiO2 coating as a reusable substrate, which can provide a possibility to increase the precession of SERS measurements.
Second, a gold nanoparticle grating is fabricated by lithographic method. The shape effect of gold nanoparticles in the grating is investigated by probing the diffraction light intensity of the array. A variation of the diffraction light intensity of the grating is revealed as rotating the polarization of the probe light. And, the peak of the diffraction spectra shifts with the increasing of the polarization angle of the probe light. Under observation of the SEM, gold nanoparticles of an ellipsoid-like shape are shown and the major axis of gold nanoparticles are parallel a direction with an averaged angle of 57.8o respect to grating direction. We thus considerably thought that this the varying of the diffraction spectra are attributed to the shifts of localized
surface plasmon resonance. In addition, the boundary effect on the shape of gold nanoparticles in the grating is explored.

▼ Raman spectroscopy has become one of the most important tools for characterizing and studying defect in graphene, due to its rapid, non-destructive and sensitive technique. Through the D-band and two edge-phonon modes (1450cm-1 & 1530cm-1) of graphene Raman bands can understand the degree of defect or disorder of graphene films. In this thesis, we prepared the nano-metal gratings by E-beam lithography and lift-off process, then using chemical vapor deposition growth of graphene layers and transfer to the metal gratings. Use the grating as medium of
surface plasmon coupling to produce SERS effect. By observing the change of D-bandãG-band and two sub-peaks intensity during different periods of gratings of Raman spectrum of graphene, explore the relationship between the size of the grating period and the Raman peak intensity and position between peaks. In the meanwhile to compare the
surface plasmon mode while gold and nickel grating structure, and also the differences of graphene Raman signals between grating structure and flat film to prove the existence of SERS effect. Besides, we also discussed certain factors which may affect intensity, such as laser excitation wavelength and polarization, and so on. Finally, we discussed graphene edge-phonon mode as the application of graphene defect detection.

▼ The development and characterization of biomolecule sensor formats based on the optical technique Surface Plasmon Resonance (SPR) Spectroscopy and electrochemical methods were investigated.
The study can be divided into two parts of different scope.
In the first part new novel detection schemes for labeled targets were developed on the basis of the investigations in Surface-plamon Field Enhanced Spectroscopy (SPFS). The first one is SPR fluorescence imaging formats, Surface-plamon Field Enhanced Fluorescence Microscopy (SPFM). Patterned self assembled monolayers (SAMs) were prepared and used to direct the spatial distribution of biomolecules immobilized on surfaces. Here the patterned monolayers would serve as molecular templates to secure different biomolecules to known locations on a surface. The binding processed of labeled target biomolecules from solution to sensor surface were visually and kinetically recorded by the fluorescence microscope, in which fluorescence was excited by the evanescent field of propagating plasmon surface polaritons. The second format which also originates from SPFS technique, Surface-plamon Field Enhanced Fluorescence Spectrometry (SPFSm), concerns the coupling of a fluorometry to normal SPR setup. A spectrograph mounted in place of photomultiplier or microscope can provide the information of fluorescence spectrum as well as fluorescence intensity. This study also firstly demonstrated the analytical combination of surface plasmon enhanced fluorescence detection with analyte tagged by semiconducting nano- crystals (QDs).
Electrochemically addressable fabrication of DNA biosensor arrays in aqueous environment was also developed. An electrochemical method was introduced for the directed in-situ assembly of various specific oligonucleotide catcher probes onto different sensing elements of a multi-electrode array in the aqueous environment of a flow cell. Surface plasmon microscopy (SPM) is utilized for the on-line recording of the various functionalization steps. Hybridization reactions between targets from solution to the different surface-bound complementary probes are monitored by surface-plasmon field-enhanced fluorescence microscopy (SPFM) using targets that are either labeled with organic dyes or with semiconducting quantum dots for color-multiplexing. This study provides a new approach for the fabrication of (small) DNA arrays and the recording and quantitative evaluation of parallel hybridization reactions.
In the second part of this work, the ideas of combining the SP optical and electrochemical characterization were extended to tethered bilayer lipid membrane (tBLM) format. Tethered bilayer lipid membranes provide a versatile model platform for the study of many membrane related processes.
The thiolipids were firstly self-assembled on ultraflat gold substrates. Fusion of the monolayers with small unilamellar vesicles (SUVs) formed the distal layer and the membranes thus obtained have the sealing properties comparable to those of natural membranes. The fusion…

G protein-coupled receptors (GPCRs) are the largest family of proteins in humans and are expressed widely throughout the body. GPCRs consist of seven-transmembrane helices that bind extracellular ligands to initiate intracellular downstream signaling via interaction with G proteins, and function in many short and long-term responses in the body, including taste, immune function, and sugar sensing. Extracellular binding and the coupled downstream signaling pathway means that GPCRs are ideal drug targets for many diseases, making them of great interest to the pharmaceutical industry. Some GPCRs have been crystallized in an effort to better elucidate the structure-function relationship to aid in the design of novel therapeutics.
The adenosine A2A receptor (A2AR) is a GPCR that has been crystallized bound to agonist, antagonist, and G protein. Although these crystal structures are informative in regards to A2AR structure when associated with binding partners, all current crystal structures truncate nearly 100 amino acids of the C-terminus. As a crystallization strategy, this truncation makes sense considering the C-terminus is long and unstructured. However, truncating roughly 25% of the protein, as well as making other point mutations calls into question the authenticity of the crystal structures in reflecting functional receptor and thus their potential value for therapeutic design.
Beyond structural studies, biophysical characterization of drug binding to receptors in vitro to predict efficacy in vivo has shifted away from measures of affinity and selectivity and towards determination of kinetic rates. Kinetic rate constants in combination with affinity and drug residence time are thought to be better predictors of drug behavior in vivo. For these reasons, this thesis focuses on experiments to characterize A2AR kinetic rate constants.
Previously, our lab showed that truncating the A2AR C-terminus reduced downstream cAMP signaling in mammalian cells, although where the effect on the signaling pathway occurred was not determined. Here, we report that truncation of the C-terminus ablates receptor association to Gαs, the first step in signaling. In this work, A2AR ligand binding kinetics, stability, and association to Gαs are characterized to better delineate the importance of interactions between receptor and stimuli in a way that is impactful to drug design.

▼ Surface plasmons, coherent oscillations of electrons in metals that can be excited with electromagnetic waves, are a key component in routing and manipulating light-matter interaction at nanometer length scales. Because of their deep-subwavelength mode volumes and strong field confinement,
surface plasmons provide a means to realize numerous innovations such as metamaterials & metasurfaces, sub-diffraction limited imaging, sensing, and cloaking. While the non-radiative decay of plasmons has been long considered to be a parasitic loss, recent research has shown that it can be harnessed for a number of applications including photothermal heat generation, photodetection, photovoltaics and photocatalysis. Despite the significant advances, research in this area is still in its infancy with devices generally suffering from low efficiencies. This thesis focuses on understanding how plasmonic nanostructures can be properly engineered to take full advantage of the non-radiatively

▼ The objective of this research was to excite multiple
surface-
plasmon-polariton (SPP) waves guided by the interface of a metal and a chiral sculptured thin film (STF). For this purpose, three different experimental set-ups were used. The data were collected for several different samples. Aluminum, magnesium fluoride, zinc selenide and sodium fluoride are the materials that were used to deposit thin films.
Both metal and chiral STFs were deposited by a thermal evaporation technique. In all cases, a 30-nm-thick aluminum film was deposited first on a pre-cleaned glass slide. Next, to deposit a chiral STF, the substrate holder in the vacuum chamber of the thermal evaporation system was tilted and rotated. The vapor flux angle, i.e., the angle between incoming vapor flux and the substrate plane, is called Xv. Chiral STFs deposited at Xv = 10 and Xv = 15 were used to understand the effects of different directions of the incoming vapor flux. Also, the thicknesses of chiral STFs were varied between 900 nm and 1500 nm. The chiral STFs were deposited in 3, 4, and 5 periods, each period being 300 nm in thickness. Besides chiral STFs, columnar thin films were deposited for comparison.
A He-Ne laser was used as a light source to illuminate the sample which was affixed to a BK7 glass prism, and the reflectance was detected by a photomultiplier detector for both p- and s- polarizations of the incident light. Graphs of the reflectance versus the angle of incidence were plotted.
If the angular location of a reflectance minimum is independent of the thickness of the chiral STF, then it is evidence of an SPP wave. Results of the experiments for Glass-slide/Aluminum/NaF-chiral-STF structure showed several reflectance minimums independent of the thickness of the chiral STF; hence, multiple SPP waves were launched. If more than one SPP wave can be launched guided by the interface of a metal and a thin film, this property can be used for many different applications including bio-chemical sensing.

▼ A tunable polarization modulator based on the periodic metal strips embedded in a polymer waveguide is presented. The periodic metallic structure is analyzed by Finite Element simulation (COMSOL). The calculation results show that the giant birefringence is formed by the selective cut-off of TE polarization over TM polarization, which makes it possible to design an efficient polarization modulator with a short conversion length. The metallic strips are made by using four-layer lift-off fabrication technology. The transmission and group indices of TE and TM modes are measured. However, it is observed that TE and TM modes cut off at same time, which does not agree with our predictions. The reason for failure is that the change in refractive indices is different from what we expected, which makes the device perform in opposite way. Finally, further suggestions are provided to modify the design so that the device can achieve its expected function.

▼ Surface plasmon resonance (SPR) spectroscopy is a rapidly growing field for chemical detection. Various SPR sensor architectures can offer high sensitivity, tunability and selectivity over a wide range of applications. Enhancements to this technique are obtained by introducing novel and modified designs capable of probing different optical regions. The contributing efforts of this dissertation aim to identify and characterize several of these platforms for use in real-world sensing applications. Herein, three basic types of SPR architectures are developed, conducting polymers as a replacement for conventional materials, a MIR-SPR sensor pad and composite-SPR sensors for selective applications. Conductive polymers represent an exciting addition to plasmonics as they offer new ways to apply SPR sensing for a reduced cost, in particular Polyaniline (PAni) has been identified in literature a possible candidate for SPR. In this dissertation several deposition methods for PAni are presented to obtain specific film parameters capable of supporting plasmonic behavior, including vacuum deposition and solution cast methods. Vacuum deposition methods exhibit good control over the thin film parameters, with roughness values (R RMS ) as low as 0.5 nm and a reduced amount of observable pin-holes. Additionally, the deposition methods described herein are applicable to the demonstration of polymer plasmonics as well the improvement of non-plasmonic applications of conducting polymers. Theoretical modelling reveals that certain films demonstrate sufficient sensitivity (~3770 nm/RIU) for SPR sensor applications. Experimental validation performed in this dissertation does not substantiate theoretical evidence, however identifies innate difficulties is the experimental demonstration and will be essential for subsequent investigations. In an attempt to expand SPR to different analytes and demonstrate a highly tunable sensor, a MIR-SPR sensing pad is developed with the capability of probing various regions within a single sample. The sensitivities and plasmonic characteristics are quantified over the MIR region with the highest sensitivities occurring between 2800 cm -1 and 2250 cm-1 (~15,200 +/- 2.2 nm/RIU). For specific MIR wavelength regimes, a 22 +/- 4% deviation is observed from theoretical values. Furthermore, discrepancies for determining the theoretical probing depth are identified and alleviated with a more robust method to verify experimental values with theoretical predictions. Finally, composite SPR materials are designed to promote further selectivity and tunability for SPR devices. Initially, a coupled waveguide
plasmon resonance MIR-sensor is described that suggests high variability within the MIR regime and is successfully applied to quantitative and qualitative hydrocarbon detection in the ppb range. Moreover, a selective
plasmon-plasmon sensor is optimized towards enhancement of sensitivity and modulation of signal by means of
plasmon coupling. The optimization of a component parts reveals good tunability for future…

▼ The production of an efficient and low cost device has been the ultimate goal in the photovoltaic cell development. The fabrication and application of nanostructured materials in the field of energy conversion has been attracting a lot of attention. In this work, applications of
surface plasmons (SPs) and photonic nanostructures to the field of energy conversion, specifically in the area of silicon solar cells and lanthanide energy upconversion (UC) luminescence applications were studied. Enhanced power conversion efficiency in bulk (single crystalline) silicon solar cells was demonstrated using an optimized mixture of the silver and gold nanoparticles (NPs) on the front of the cell to tackle the negative effect in the Au NPs plasmonic application. Then, a comparison of identically shaped metallic (Al, Au and Ag) and nonmetallic (SiO2) NPs integrated to the back contact of amorphous thin film silicon solar cells were investigated to solve a controversy issue in literature. The result indicates that parasitic absorption from metallic NPs might be a drawback to the SPs enhancement. A cost-effective fabrication of large area (5x5 cm2) honeycomb patterned transparent electrode for “folded” thin film solar cell application by combining the nanosphere lithography and electrodeposition were realized. Furthermore, the SPs enhanced tunable energy upconversion from NaYF4:Yb3+/Er3+ NPs in nanoslits were also demonstrated, our results shows that the relative red/green emission can be controlled by different plasmonic mode coupling.

▼ Surface plasmon resonance (SPR) has found wide applications in sensing down to molecular level due to its extreme sensitivity to change of dielectric properties. An unavoidable effect in SPR is surface deformation (thermal bump) due to local heating by incident laser light used in SPR excitation. In addition, the change in reflection phase from an SPR-supported metal film could also contribute to the SPR signal variation, and thus proper handling of measured SPR signals is very important in order to broaden its potential applications. Here a simple Fabry Perot (FP) interference technique for measuring, simultaneously, the thermal bump as well as the reflection phase shift of the gold film used for SPR excitation is reported. The FP signal change is dominated by the appearance of the thermal bump while it is small for the effect of the reflection phase shift due to the change of dielectric property of the metal. To support the experimental results, model simulations for the SPR system are performed and good agreement with the experiment is obtained. The effect of the thermal bump on the resonance of surface plasmon is also investigated and a polarization-dependent reflection phase shift is observed in SPR. Since both amplitude and phase can be measured, our method could lead to a better characterization of SPR and can also be applied to the study of active metasurfaces under external excitation.

▼ Surface plasmon polaritons are highly localised field oscillations that propagate along interfaces between a dielectric and a metal. Their localised fields make them potential signal carriers between integrated circuits, replacing electronic signals, to allow wider bandwidths and less power dissipation. End-fire coupling is a simple, compact method for exciting surface plasmon polaritons with potential for high coupling efficiency. However, the parameters that determine the mechanism's optimisation are not well understood. We present a semi-analytical model of the end-fire mechanism, in which a free-space incident beam excites a surface plasmon polariton in a configuration with a single transverse dimension. We first model coupling into a surface plasmon polariton on an air-lossless metal interface. Our projection method, a key modelling component, uses an energy conservation expression which includes contributions from both propagating and evanescent fields, which become significant for near-field sources. By optimising the incident beam width and position, we find maximum coupling efficiencies of up to ~90% over the wavelength range of λ∈[0.5,1.8] μm, averaging ~80%. We also find that each excitation produces not only the primary surface plasmon polariton, but also a transversely propagating secondary surface plasmon polariton. We then adapt our method to simulate lossy plasmonic materials, replacing the lossless metal with silver, gold, titanium nitride and zirconium nitride using their values from literature. By optimising the incident beam parameters, we find that the coupling efficiencies of all four materials reach 87% over the range λ∈[0.38,2] μm. These high coupling efficiencies are explained using an impedance-matching argument, concluding that most of the surface plasmon polariton field is in the dielectric, not the plasmonic material. Using a simple analytical model, we show that there is a universal relationship between the optimum beam width and position.

Kinetics of insulin - insulin receptor interaction using a surface plasmon resonance (SPR).

▼ Type 2 diabetes or adult onset diabetes, has been a global epidemic for the past two decades, and the number of new cases accelerates every year. Insulin resistance is one of the major factors behind this, wherein the insulin receptor, which signals to regulate glucose levels, based on the hormone insulin, loses its sensitivity. Obesity is one other major concern which is caused due to the improper balance between the caloric intake and the energy utilized. Gastric bypass surgeries (GBP) are performed to avert obesity. However, a beneficial side-effect is that the state of insulin resistance is reset to near baseline levels within a few days after the procedure. The reason behind this remains unexplained, with possible humoral effects, hypothesized to occur after the bariatric procedure.
In this work, high-five insect cell line was utilized to recombinantly produce full length insulin receptors (IR). However commercially sourced IR ectodomains (eIR – soluble version of the full length IR with the completely extracellular α subunits along with extracellular and transmembrane regions of the β subunit), were used to study the interaction. Measuring the kinetics of IR-insulin interactions is critical to improving our understanding of this disease. In this study, a multiplex surface plasmon resonance (SPR) assay was developed for studying the interaction between insulin and the eIR. A scaffold approach was used in which anti-insulin receptor monoclonal antibody 83–7 (Abcam, Cambridge, UK) was first immobilized on the SPR sensorchip by amine coupling, followed by eIR capture. The multiplex SPR system (ProteOn XPR36TM, Bio-Rad Laboratories, Hercules, CA) enabled measurement of replicate interactions with a single, parallel set of analyte injections, whereas repeated regeneration of the scaffold between measurements caused variable loss of antibody activity. The main approach was to replicate the physiological IR-insulin interaction using this assay. It was also observed that insulin at higher concentrations tend to form dimers and hexamers in solution.
This was tested using size exclusion chromatography analysis and proved to be true. Therefore an alternative analyte with the similar binding properties and affinity of insulin and at the same time with reduced self- association characteristics was explored. Lispro, the analogue of insulin with reduced self-association properties (generated by swapping of residue 28 and 29 with Lys and Pro respectively) was finally used to study the interaction with eIR.
Interactions between recombinant human insulin with eIR-A (A isoform of the insulin receptor ectodomain) followed a two-site binding pattern (consistent with the literature), with a high-affinity site (dissociation constant KD1 = 38.1 ± 0.9 nM) and a low-affinity site (KD2 = 166.3 ± 7.3 nM). The predominantly monomeric insulin analogue Lispro had corresponding dissociation constants KD1 =73.2 ± 1.8 nM and KD2 =148.9 ± 6.1 nM, but the fit to kinetic data was improved when conformational change factor was included in which…

Resumo: Singularidades de fase simulam um "esqueleto" do campo eletromagnético de tal forma que várias informações sobre a distribuição do campo e o comportamento físico podem ser obtidas. As singularidades permeiam todos os sistemas ópticos genéricos e são imunes à perturbação do sistema. Nesta tese estudamos suas propriedades em várias situações de interesse físico, distribuídas da seguinte forma: No Capítulo 1 introduzimos o conceito de singularidade de fase bem como sua definição formal e sua relação com o momento angular de um feixe de luz. No Capítulo 2 entraremos no regime nanométrico da luz
com o objetivo de criar um campo evanescente caracterizado por uma dinâmica rica de singularidades de fase com possiveis aplicações na manipulação de objetos em nanoescala. No Capítulo 3 continuaremos no regime nanométrico da luz com o objetivo de criar e compreender a física de um plasmon de superfície possuindo uma singularidade de fase. Mostramos que é possível criar um campo plasmônico, acoplado à superfície de um metal, possuindo vórtices ópticos. No Capítulo 4 tratamos de luz parcialmente coerente, onde estudamos singularidades de fase em campos cuja natureza é estatística. Nosso trabalho conclui que é possível utilizar difração para medir a carga topológica de feixes parcialmente coerentes. Por fim, no Capítulo 5, as conclusões serão estabelecidas bem como as perspectivas futuras
Phase singularities form a "skeleton" of the electromagnetic field such that various information about the field distribution and its physical behavior can be obtained. The singularities permeate
all generic optical systems and are immune to perturbations. In this thesis we study their properties in various situations of physical interest distributed as follows: In Chapter 1 we introduce the concept of phase singularity and its formal definition together with its relationship with the angular momentum of a beam of light. In Chapter 2 we proceed to the nanometer domain of light to create an evanescent field with a rich phase singularitiy dynamics aiming at possible applications in the manipulation of objects on a nanoscale. In Chapter 3 we will continue in the nanometer domain and our goal will be to create and understand the physics of a surface plasmon having a phase singularity. We show that it is possible to create a plasmonic field, coupled to the metal surface, possessing optical vortices. In Chapter 4 we will enter into the optical statistical domain, where the study of phase singularities in partially coherent fields will take place. Our results indicate that it is
possible to use diffraction to measure the topological charge associated with partially coherent light beams.…

▼ Real-time biomolecule interaction analysis (BIA) sensor chips are widely used in biomedical testing. Over the developed techniques,
surface plasmon resonance shows the most promising for these applications. Optic fiber based SPR sensors exhibit the advantage of low-cost but it is difficult to integrate with microfluidic systems. The angle variation detection is promising to integrate with microfluidic system for real-time detection. However, conventional angle-variation SPR detection schemes are usually limited by the relatively big size of the incident light spot and the difficulty for real-time optical image observation. In addition, an expensive goniometer is required to obtain precise angle measurement. Therefore, it is essential to develop a system for simultaneously optical image observation and SPR detection without using the moving part.
This work presents a TIRF objective-based
surface plasmon resonance (SPR) system for simultaneously image capturing and wavelength- resolved SPR detecting for microfluidic applications. The light from a low-cost tungsten bulb passes through a designed light stop and polarizer is used as the light source for SPR detecting. The light spot is reduced to around 15 ïm after passing through the 60X objective lens, resulting in a higher spatial resolution for SPR detection in microfluidic channels. Moreover, the designed confocal scheme makes the system capable of simultaneously optical observation and SPR detection without scanning the wavelength or switching the optical system. Results show that the developed system is capable of detecting samples of refractive index in the range from 1.0 to 1.38 with a sensitivity of around 3417 nm/RIU. The developed system provides a simple yet high performance method for on-site detecting the SPR spectra anywhere inside a microfluidic device.
The system was constructed under a home-built microscope system. A tungsten bulb was used for the light source for SPR excitation. The light passed through a designed light-stop with a 1.0 mm hole to obtain light beam with continuous wavelength. The light beam then passed through the polarizer (TM mode) and deflect using a TIRF objective lens for SPR excitation. With this approach, the incident light beam can be further condensed into a small light spot such that the spatial resolution can be enhanced.
The system setup for simultaneously image capturing and high spatial SPR detection. The reflected light beam was collected using a multimode optic fiber and analyzed with a high performance spectrometer for SPR analysis. A low N.A. objective lens was used for simultaneously capturing the image while SPR detection. Therefore, microscopic image and SPR analysis can be achieved in a simple system without moving or scanning parts. Results show that the off-axis distance of 5.8 mm has the greater SPR performance.
This study has measured the signal of SPR upon TIR Objective successfully. Whether we changed the d off-axis distance corresponding to a different angle of incidence, or changed in the refractive index…

▼ This study investigates phenomena of
surface plasma induced by an incident electromagnetic wave on a
surface.
Surface plasmon wave is a consequence of the collective shock behavior of free electrons within the metal excited by external electromagnetic field. Owing to the shielding effect of high electron density in metal, the electron waves cannot penetrate the metals, but generate a confined longitudinal wave on the
surface. This wave is called non-radiative
surface plasmon waves. In this study, electromagnetic waves are obtained by solving Maxwell's equations from COMSOL software using the finite difference frequency domain method. The effects of wavelength and incidence angle of electromagnetic wave and optical properties of materials on thermal fields near a
surface are presented.

▼ In 1998 Ebbesen and co-workers discovered the extraordinary optical transmission
through a subwavelength silver nano hole array. Here we measure
the transmittance of a subwavelength gold square nano hole array. We study
the transmittance as a function of hole size and as a function of array size.
Comparing the results of the 2500 square micrometer array with the 930 square micrometer array, we
conclude the array size is an important factor for the transmittance profile.
Transmittance of the 2500 square micrometer array follows a clear Fano-profile and has a
larger transmittance.
For the transmittance dependent on hole size, we can make a distinction
between holes that do not support transverse electromagnetic waves, i.e. that
are in cutoff, and holes that are not in cutoff. The normalized transmission
for arrays that are not in cutoff is not dependent on hole size. This result
shines a new light on the extra ordinary transmission.

This dissertation reports the novel characterization technique based surface plasmon resonance (SPR) spectroscopy. First, solution-based fabrication of gold grating film for use as a SPR sensor chip, gold nanoparticles (AuNPs) grating films were fabricated by imprinting technique. The SPR measurements of this substrate were carried out on a SPR device in the grating–coupling configuration with an excitation source of He-Ne layer (λ = 632.8 nm) and multimode surface plasmon excitations were observed upon irradiation with white light. From both SPR measurements, imprinted AuNPs grating substrate provided strong SPR excitation signals. The sensitively shift upon organic thin film deposition were observed. Second, transmission surface plasmon resonance (T-SPR) enhancement by localized surface plasmon resonance of metal nanoparticles (i.e., AuNPs and silver nanoparticles (AgNPs)). AuNPs were directly deposited on gold grating surface. The growth mechanism of AuNPs on gold surface was investigated by UV-visible spectroscopy and SPR spectroscopy. The TSPR results show a possibility of hybrid excitation of localized and propagating surface plasmon. The T-SPR signal enhancement of this hybrid SPR substrate was observed while the multilayer films were deposited on its surface. Furthermore, distance-dependent SPR coupling between metal nanoparticles and gold grating surface was further study. The distance between AgNPs and gold grating surface was controlled by number of bilayers ultrathin film deposition. The distance-dependent T-SPR response of peak position and intensity showed distinctive changes when the intermediate layer was 10 bilayers (-17 nm) thick. This substrate was explored in switchable pH sensor. The T-SPR spectrum sensitively changed as the pH switched from acidic (pH 2) and alkaline (pH 12) conditions by the swelling/shrinking of the polyelectrolyte film between the AgNPs and the gold grating surface.

▼ Hybridization of quantum emitters and plasmonic nanostructures has attracted much attention over the last years, due to their potential use as plasmon-based nanolasersor to achieve long-range quantum bit entanglement. Recent theoretical studies suggest that the plasmonic field can induce efficient cross-talking between emitters and lead to the formation of collective superradiant states. In this thesis, we developed a theoretical modelable to analyse collective effects in large ensemble of dipoles coupled by an electromagnetic nanoresonator. We experimentally investigated the plasmon-mediated superradiance of organic emitters grafted at a well-controlled distance from a metal nanosphere at room temperature. We report on the measured decay rates of these hybrid structures at the ensemble and single object levels. We find that the decay rate increases i) with the number ofemitters and ii) as the spacing between the emitters and the metal core decreases, a direct and clear evidence of plasmonic superradiance. This trend was observed for two types of hybrid structures, differing both by the size of the metal core and the type of organic dye used as emitter. The observation of plasmonic superradiance at room temperature opens questions about the robustness of these collective states against decoherence mechanisms.This robustness is of major interest for potential applications of quantum systems at room temperature.
Placer des nanostructures plasmoniques à proximité d’émetteurs quantiques est une approche prometteuse pour concevoir des nanolasers plasmoniques ou réaliser l’intrication de bits quantiques à longue distance. Des études théoriques récentes suggèrent que le champ plasmonique peut induire un couplage efficace entre émetteurs et mener à la formationd’états collectifs superradiants. Dans ce travail de thèse, nous avons développé un modèle théorique afin d’analyser les effets collectifs pour un ensemble de dipoles couplés à un nanorésonateur électromagnétique. Nous avons étudié expérimentalement la superradiance plasmonique d’émetteurs organiques greffés à une distance contrôlée d’une nanosphère metallique,à température ambiante. Nous avons mesuré le taux de relaxation de ces structures hybrides, en ensemble et à l’échelle de l’objet unique. Nous observons que le taux de relaxation augmente i) avec le nombre d’émetteurs et ii) lorsque la distance entre les émetteurs et le coeur métallique diminue, une preuve directe et claire de la superradiance plasmonique.Cette tendance a été observée pour deux types de structure hybride, différentes par la taille du coeur métallique et par le type de molécule utilisée comme émetteur. L’observation de la superradiance plasmonique à température ambiante ouvre des questions sur la robustesse d’un état superradiant contre des mécanismes de décohérence. Cette robustesse présente un intérêt majeur pour des applications potentielles de systèmes quantiques à température ambiante.

▼ The epithelial sodium channel (ENaC) is responsible for sodium reabsorption in the distal convoluted tubules of the nephron in the kidneys. ENaC is a transmembrane protein with N and C-termini located in the cytosol and a larger extracellular loop containing a wrist, palm, beta-ball, thumb, knuckle and finger. Due to ENaCs hydrophilic and hydrophobic nature, isolation and purification while still being functional is not well understood. A 6x histidine tag was engineered into the extracellular loop of αENaC, referred to hereon as αHis2-αENaC, and then was subcloned in the yeast expression vector pYES2/NTA. pYES2/NTA/αHis2-αENaC was transformed into S1, MATα ura3-52 leu2-3,112 trp1-289 his7-2 ade5-1 lys2::InsE-4A, and BY4742, MATα his3∆1 leu2∆ lys2∆ ura3∆ ygr204::kanMX4, yeast strains. Serial dilution assays, time-course expression trials, immobilized metal affinity chromatography (IMAC) and western blot analysis were employed to purify and verify expression of αHis2 in each strain of Saccharomyces cerevisae. ENaC peptides of each subunit were previously engineered and subcloned in the bacterial expression vector pGEX-4T-2. Immobilized substrate affinity chromatography (ISAC) was employed to purify peptides.
Surface Plasmon Resonance (SPR) was conducted between ENaC peptides and whole subunit αHis2-αENaC. We report that the interactions of the palm and thumb region of βENaC, independently, between the whole αENaC subunit gave kinetic constants in the non-covalent range, potentially being an inter-subunit binding domain. Additional studies would use longer peptides, thought to be portions/ whole binding domains, to further elucidate inter- subunit binding regions.
