▼ This thesis was motivated by the different properties exhibited by magnetic nanoparticles when compared with the bulk. For example the coercivity and magnetocrystalline anisotropy vary with the particle size and the finite particle size can affect the spin-wave dispersion. When the nanoparticle radius becomes small enough it is possible to observe superparamagnetism with negligible hysteresis. The transport properties can also be different in nanoparticle composites when compared with the bulk. It is particularly interesting if the nanoparticles have a degree of electronic spin polarization because it is then possible to observe spin-dependent tunnelling. This thesis reports the results from a study of the structural, magnetic, and electronic properties of two partially electronically spin-polarized nanostructured compounds, iron-nickel alloy and magnetite, that were made using a new arc-discharge method, ion implantation and annealing, and a co-precipitation method. It was found that permalloy powders could be made by arc-discharge where there were a range of particle sizes from nms to 10s of microns. Magnetoresistance was observed where it is due to the ordinary magnetoresistance and spin-dependent tunnelling between the particles. It was also possible to make magnetite using the arc-discharge process and the powders contained nanoparticles, large faceted nanoparticles, and larger particles in the 10s of micron range. The temperature dependence of the saturation magnetization changes at 127 K, which can be attributed to the charge-ordering Verwey transition. A large magnetoresistance was observed and attributed to spin-dependent tunnelling between the magnetite particles. It was less than predicted due to a spin-disordered interfacial region. The electrical resistance was modelled in terms of small nanoparticles coating the larger particles and electrostatic charging during tunnelling between small nanoparticles. Magnetite powders were also synthesized via a chemical co-precipitation method where nanoparticles with diameters of ~14 nm were observed. The Verwey transition was only observed in the zero-field cooled field-cooled magnetization for the arc-discharge powders. It was observed for the magnetite powders made using both methods in the temperature dependence of the saturation moment. The saturation magnetic moment for powders made using both methods has a power law dependence on temperature with an exponent of 3/2 at low temperatures and a higher value above the Verwey transition temperature 2. There was also a large magnetoresistance due to spin-dependent tunnelling for magnetite nanoparticle made using a chemical co-precipitation method and the electrical resistance could be modelled in terms of electrostatic charging during tunnelling. NixFe₁₋x nanoparticles were made for the first time by ion beam implantation. Small superparamagnetic nanoparticles occurred after implantation. The saturation moment after implantation did not follow the Bloch’s T³/² for x=0.82, which is likely to be due to spin-waves… Advisors/Committee Members: Williams, Grant, Kennedy, John V..

▼ Nanotechnology has had a great impact in several industries such as medical and electronics, and more recently in the oil and gas industry. In particular, magnetic nanoparticles are receiving great attention in the oil and gas industry because of their capability to enhance down-hole imaging. Ferrites are selected for this kind of applications because of the magnetic properties they exhibit such as high magnetic susceptibilities and high saturation magnetization. These properties could enhance the resolution of currently used geophysical techniques for imaging oil and gas reservoirs or increase the negative contrast in magnetic resonance imaging (MRI). The Colvin group is well known for the synthesis of monodisperse ferrite nanocrystals, in particular Fe3O4. The research presented in this dissertation extends the previous works and shows the synthesis and physical characterization of spinel ferrites (MFe2O4, M= Mn2+, Co2+, Ni2+, and Zn2+) with a narrow diameter distribution. A very stringent control of the composition and size of the nanocrystals is one of the achievements of this work (Chapter 4). By varying these parameters, size and composition, we can tune the magnetic properties. In addition, characterization of their magnetic properties depending on their size, composition and distinctive surface areas is explored and discussed. The effect of other phenomena such as aggregation on the magnetic properties of nanoparticles was also studied (Chapter 5). This effect becomes important when aggregation is controlled causing a significant enhancement on the magnetic properties. For this reason, the synthesis and characterization of controlled magnetic ferrite nanoclusters was investigated. Magnetic susceptibilities observed in ferrite nanoclusters were much higher than any commercial nanomaterial available and synthesized isolated spinel ferrites. Finally in Chapter 6, we explore the use of nanomaterials herein prepared for several applications, including magnetic separation, MRI contrast agents and contrast agents for down-hole imaging for the oil and gas industry. We utilize magnetic separation as a tool to separate magnetic materials based on composition of nanoparticles. For MRI contrast agents, doping of metals for Fe2+ ions, size and aggregation of nanoparticles were found to significantly influence the MRI signal. Lastly, synthesized magnetic nanoparticles were found to have magnetic susceptibilities three times higher in solution and powders than any commercially available nanomaterial. Due to these high magnetic susceptibilities they could have great potential for down-hole imaging in the oil and gas industry. Advisors/Committee Members: Colvin, Vicki L. (advisor).

▼ The use of stents in the treatment of atherosclerosis leads to a potential risk of restenosis, caused by neointimal hyperplasia. Neointimal hyperplasia is mainly caused by an injury to the endothelial layer of the blood vessel followed by the proliferation of smooth muscle cells into the lumen of the blood vessel. To address this, we designed a magnetically-guided drug delivery system to locally deliver heparin to a stented artery. The nanoparticles were synthesized, characterized, and tested on relevant human cell lines. The particles were non-toxic to human smooth muscle cells, endothelial cells, and fibroblasts. They reduced the proliferation of the smooth muscle cells and increased the proliferation of endothelial cells at concentrations as low as 10 μg/mL. The particles also shifted the smooth muscle cells from their synthetic phenotype to their contractile phenotype. The capture of the nanoparticles by the stent struts, under relevant magnetic field and blood velocity was modeled using COMSOL Multiphysics. The coronary artery was modeled using a 2D axisymmetric model with stainless steel stent struts. A Magnetic field of 1 T was applied to magnetize the stent struts. Three different strut geometries were compared for their effect of the capture efficiency. The model had a capture efficiency 0f 34-42%, which is comparable to models using the same particle sizes. Ex vivo organ culture studies using porcine right coronary arteries were performed. The arteries were conditioned either statically in cell culture flasks or dynamically in an organ culture bioreactor. Nanoparticles reduced intimal thickening in and expressed contractile properties in the treated arteries compared to the controls. We were successfully able to synthesize heparin-coated magnetic nanoparticles and achieve high heparin loading. Particle capture efficiency around the stent in the ex vivo porcine artery model was found to be similar to that predicted by the computational model. Consistent with the prior results of systemic heparin delivery, the nanoparticles reduce the proliferation and dedifferentiation of vascular smooth muscle cells while promoting endothelialization, both in vitro and ex vivo. Thus, these particles may be a promising treatment option for neointimal hyperplasia. . Advisors/Committee Members: Delphine Dean, Olin T Mefford, Jeoungsoo Lee, Ulf Schiller.

▼ Incorporating nanoparticles and polymers into one composite material have opened new pathways for generating novel material structures and advancing the properties of conventional materials. The developments in the field of nanocomposites have been accelerated by the progress in fabrication of nanoparticles with designed shape and precise size control, surface modification techniques covering a variety of nano-scale materials including clay sheets, carbonaceous materials, metal oxide particles, etc., as well as new syntheses of polymers with targeted architecture and functionality. The control of interfacial interactions is the key to property enhancement of almost all nanocomposite materials. Grafting polymer chains directly onto the surface of nanoparticles is a relatively new approach for obtaining novel nanocomposite structures and it offers better control of grafting density and maximizes the interfacial interactions between nanoparticles and polymeric matrices. The first project in this thesis describes the preparation of nanocomposites via surface initiated polymerization of block copolymer chains directly from the surface of montmorillonite clay. A ‘graft-from’ synthesis protocol was developed for the preparation of the nanocomposites. Comprehensive material characterization was performed to understand the structure and properties of the nanocomposites. Crystallization behavior of the bulk material and optical properties of nanocomposite films were examined. The relationship between material synthesis, structure and properties is also discussed in these chapters. The second project involves grafting polyelectrolytes onto magnetic nanoparticles for the application of electromagnetic imaging in high temperature, high salinity gas and oil reservoir environments. The fabrication of magnetic nanoparticles is described with a focus on both size control and achieving colloidal stability. The synthesized nanoparticles were used as core materials for their outstanding magnetic properties. Subsequent surface functionalization and a ‘grafting-to’ method was developed to coat the nanoparticles with a surface layer of polyelectrolytes, which provides nanoparticles with excellent transport mobility for high temperature, high salinity aqueous flow conditions through porous rock and sediment.

▼ The present work is divided into two sections. The first section deals with the synthesis of regenerable adsorbents for the removal of arsenic from contaminated waters. An adsorbent based on carboxymethylated polyethylenimine grafted agarose gels was synthesized and characterized as a regenerable synthetic ferric oxide adsorbent with high capacity for arsenate ions at pH 3.0. Similarly, four metal ion chelating adsorbents based on dipicolylamine were synthesized and characterized with respect to their Cu(II), Fe(III) and As(V) adsorption capacities. The most efficient adsorbents were Nov-PEI-DPA and Nov-TREN-DPA. Additionally, a commercial ion exchange resin was modified with permanganate to oxidize arsenite into arsenate. A complete oxidation-adsorption system was proposed in which a column packed with the oxidation resin was connected in series with an adsorbent column composed of the polyethylenimine grafted agarose gels.The second section involved work with magnetic nanoparticles. First, composite adsorbents consisting of magnetic particles encapsulated within agarose beads with and without grafted iminodiacetic acid (IDA) chelating groups were synthesized. The adsorption capacity of the adsorbents for Cu(II), Fe(III) and As(V) at different concentrations was investigated. Batch experiments were carried out to determine the Fe(III) and As(V) adsorption isotherms for the magnetic Novarose-IDA. Regenerability of the adsorbent was achieved with a pH change of the inlet solution, without affecting its magnetic or adsorption properties.Magnetic composite particles were synthesized for biomedical applications. First, magnetic nanoparticles were coated with silica and then used for gold nanoshell production. These nanoshells were functionalized with a Brij S10 derivative, containing carboxylic groups, using dodecanethiol as a bridging agent to incorporate a fluorescent biomolecule.Finally, magnetic and gold particles were encapsulated in PLGA nanoparticles. Docetaxel was loaded on these multifunctional nanoparticles and released studies were performed at 37°C. The presence of magnetite, colloidal gold and gold nanoshells in the PLGA nanoparticles was revealed by the coloration acquired by the polymeric nanoparticles. The release of drug from the polymeric nanoparticles showed a biphasic behavior with an initial burst followed by a prolonged slow release. There was no effect of the presence of magnetic or metallic particles on docetaxel release.

▼ The confluence of intriguing size and morphology dependent optical and chemical properties with versatile application in various fields, such as energetic and magnetic makes monometallic nonmaterial of high fundamental scientific interest. However, the challenge that needs to be addressed is to achieve their synthesis with a rational control on their dimensions, morphology and dispersion for the widespread applications of these materials. In addition to synthesis, achieving long-lasting stability of nonmaterial becomes imperative in order to realize their potential applications. Miniaturization in size of particles results in an increased surface to volume ratio, conducing especially reactive metal nanoparticals prone to oxidation. This thesis describes the synthesis of nearly monodiperse colloids of metallic and intermetallic nanoparticles using solvated metal atom dispersion method and digestive ripening facilitated interatomic diffusion process. Our aim is to understand the combinatiorial effects of nanosizing and stability on the functional properties of these nanomaterials. Towards this Direction, we investigated Co, A1 and Mg monometallic, and Au/Ag-In and Au-Sn intermetallic nanoparticle systems. Chapter 2 Describes the synthesis, detailed characterizations and magnetic properties of nearly monodisperse cobolt nanoparticles(<5nm) synthesized using a hydride synthetic protocol, solvated metal atom diserion method. The as-prepared cobalt nanoparticles in this size range exhibit intrinsic instability towards Oxidations. After 30 day of exposure to air, magnetic measurements showed drastic degration in saturation magnetization and complete conversion to antiferromagnetic cobalt oxide was confirmed. In order to achieve their stability, a heat treatment was applied to decompose the organic solvent and capping agent, resulting in carbonization of solvent/ligand around the surface of cobolt nano particles. Controlled and optimized annealing at different temperatures resulted in the formation of hexagonal closed packed (hcp) and fape-centered cubic (fcc) phases of metallic cobalt. Remarkably, the corresponding heat treated samples retained their rich magnetic behavior even after exposure to air for a duration of one year. Compared to un-annealed samples, magnetization values increased two-fold and the corecivity of nanoparticles exhibited strong dependence on the phase transformation of cobolt. Chapter 3 Deal with an exploratory study of the synthesis, characterization, and stabilization of nanometer-sized enegetic material, aluminum. Highly monodisperse colloidal aluminum nanoparticles (3.1‡ 0.6 mm) were prepared by using hexadecy amine (HAD) as the capping agent tetrahydrofurma as a coordinating solvent in the SMAD method. Since such small particles are highly prone to oxidation, a support materials is required for their stabilization. Stability has been achived by carbonization of the capping agent on the surface of A1 nanoparticles by carrying out thermal treatment of A1-HAD nanoparticles at a modest… Advisors/Committee Members: Jagirdar, Balaji R (advisor).

▼ Neural stimulation techniques for eliciting calcium influx can elucidate the physiological roles of specific neural populations. To overcome some of the limitations of existing techniques such as poor specificity and noxious effects of heat, I developed a technology for non-invasive control of neural activities using magnetic forces and magnetic nanoparticles (MNPs) which offer deep tissue penetration and controllable dosage. Extensive investigations with different neuro-toxins and experimental conditions support that the mechanism of magnetic stimulation that involves membrane-bound MNPs transducing magnetic forces into mechanical stretching of the cell membrane to enhance the opening probability of mechano-sensitive N-type calcium ion channels to induce calcium influx.Making use of the ability of neural networks to actively regulate their ratio of excitatory to inhibitory ion channel/receptor, I also performed chronic magnetic stimulation on fragile X syndrome (FXS) model neural networks. We found that chronic magnetic stimulation reduced the density of N-type calcium ion channels whose expression is increased in FXS. This technique demonstrates the potential of using bio-magnetic/mechanical forces to modulate expressions of mechano-sensitive ion channels where they are over-expressed in diseases such as abnormal nociception.Nonetheless, there are still a few areas where the technique can be improved. Firstly, it is the use of MNPs with more uniform properties to have greater control on magnetic stimulations. Secondly, the technique needs to be useful for in vivo studies. Therefore, I started researching on magnetotactic bacteria (MTB) which produce biological MNPs with superior properties such as uniform sizes and highly homogenous magnetic properties with the goal of harvesting MNPs from them.MTB, however, grow extremely slowly and the number of MNPs produced/bacterium is low. One way to overcome this problem is to evolve MTB over-producers of MNPs but this strategy is constrained by the absence of a selection platform that is quantitative and offer high throughput. To overcome this problem, I combined random chemical mutagenesis and selection using a magnetic ratcheting platform to generate and isolate MTB over-producers that produce twice as many MNPs/bacterium after 5 rounds of mutation/selection. I next designed a magnetic microfluidic device and demonstrate as a proof of concept, that it can be coupled to a bioreactor for high throughput microfluidic selection of MTB over-producers.

Surface modification of electrodes becomes a powerful process to improve the performance of organic electronic devices such as organic light emitting diodes (OLEDs) and organic photovoltaic cells (OPVs), boosting their further commercialization. Effective improvement can be achieved by introducing several types of nanoparticles onto the electrodes. Magnetic fields also have influence in the organic electronics, due to charge transport mechanisms of organic semiconducting materials. Therefore, magnetic nanoparticles are of particular interest. Magnetic γ-Fe2O3 nanoparticles have been produced using diblock copolymer reverse micelles method. The processes were elucidated in detail by Raman spectroscopy to reveal the iron oxide evolution. Compositional and structural information of individual γ-Fe2O3 nanoparticles were also characterized thoroughly by transmission electron microscopy (TEM) equipped with energy-dispersive X-ray spectroscopy (EDX) and electron energy loss spectroscopy (EELS), while their magnetic properties of the nanoparticles arrays were also evaluated by superconducting quantum interference device (SQUID) magnetometer. The low temperature annealing process was developed to facilitate the incorporation of γ-Fe2O3 nanoparticles in practical devices. Introducing γ-Fe2O3 nanoparticles onto the anode of basic OPV devices showed a positive effect on performance during the preliminary test. By using several methods, dispersion of γ-Fe2O3 nanoparticles can be tuned, examined by disLocate which is a comprehensive suite of tools for quantitative dispersion analysis. Additionally, the size of the nanoparticles can be changed simply by changing the loading ratio of FeCl3 below the maximum loading which was determined by quantum mechanical mapping using atomic force microscopy (AFM-QNM). With high control in terms of size and dispersion, the magnetic γ-Fe2O3 nanoparticles are ready to be employed to study the surface modification and magnetic effect on organic electronic devices.

▼ Despite the large body of literature describing the synthesis of magnetic nanoparticles, few analytical tools are commonly used for their purification and analysis. Due to their unique physical and chemical properties, magnetic nanoparticles are appealing candidates for biomedical applications and analytical separations. Yet in the absence of methods for assessing and assuring their purity, the ultimate use of magnetic particles and heterostructures is likely to be limited. For magnetic nanoparticles, it is the use of an applied magnetic flux or field gradient that enables separations. Flow based techniques are combined with applied magnetic fields to give methods such as magnetic field flow fractionation and high gradient magnetic separation. Additional techniques have been explored for manipulating particles in microfluidic channels and in mesoporous membranes. This thesis further describes development of these and new analytical tools for separation and analysis of colloidal particles is critically important to enable the practical use of these, particularly for medicinal purposes. Measurement of transport of nanometer scale particles through porous media is important to begin to understand the potential environmental impacts of nanomaterials. Using a diffusion cell with two compartments separated by either a porous alumina or polycarbonate membrane as a model system, diffusive flux through mesoporous materials is examined. Experiments are performed as a function of particle size, pore diameter, and solvent, and the particle fluxes are monitored by the change in absor- bance of the solution in the receiving cell. Using the measured extinction coefficient and change in absorbance of the solution as a function of time, the fluxes of 3, 8, and 14 nm diameter CoFe2O4 particles are determined as they are translocated across pores with diameters 30, 50, 100, and 200 nm in hexane and aqueous solutions. In general, flux decreases with increasing particle size and increases with pore diameter. We find that fluxes are faster in aqueous solutions than in hexane, which is attributed to the hydrophilic nature of the porous membranes and differences in wettability. The impact of an applied magnetic flux gradient, which induces magnetization and motion, on permeation is also examined. For larger membrane pore diameters, applied magnetic fluxes increase the rate of transport of 14 nm CoFe2O4 particles more than that of 3 or 8 nm diameter particles, reflecting their differences in susceptibility. However, larger particles are excluded from membranes with small diameter pores, consistent with magnetic interparticle attractions that reversibly induce magnetic aggregation. Surface chemistry plays an important role in determining flux through porous media such as in the environment. Diffusive flux of nanoparticles through alkylsilane modified porous alumina is measured as a model for understanding transport in porous media of differing surface chemistries. Experiments are performed as a function of particle size, pore diameter,… Advisors/Committee Members: Mary Elizabeth Williams, Dissertation Advisor/Co-Advisor, Raymond Edward Schaak, Committee Member, Christine Dolan Keating, Committee Member, Kyle Jeffrey Magnuson Bishop, Committee Member.

▼ Glucose regulation is compromised in diabetic patients and hence diabetes is characterized by accumulation of glucose in blood. As a standard practice diabetic patients usually self-administer subcutaneous insulin injections daily, which are usually associated with pain, tissue necrosis, microbial contamination and nerve damage to local areas. Glucose-responsive implantable devices have provided a hope for a brighter future of diabetes management. However, one of the limitations of such devices is their refill requirement, which often requires surgical procedures leading to lower patient compliance. To overcome this limitation led to the idea of reusing insulin after it has been in the body circulation system and later becomes residues. To make this idea work, the first step proposed in this thesis is to tag insulin with magnetic nanoparticles and then to use a magnetic guidance system to bring it back the residue insulin to the implanted device before it can go to the clearance sites. Obviously, the precondition for the foregoing idea to work is to make sure that insulin’s conformation is not affected by the attachment with magnetic nanoparticles. This thesis was designed to study this precondition. The hypothesis is that the insulin’s conformation will not be affected by the attachment with the magnetic nanoparticles. Two specific objectives are: (1) assessment of the feasibility of potential capturing techniques and analysis of the attachment of insulin onto the magnetic nanoparticles to confirm the attachment; (2) measurement of the insulin’s conformation before and after it is attached with the magnetic nanoparticles. The spectroscopy techniques, including Fourier transform infrared, circular dichroism, absorbance and fluorescence spectroscopy, were used to conduct data collection and analysis. All four of these spectroscopies provide important information concerning the research objectives of this thesis. The results from the fluorescence and absorbance spectroscopy confirm the attachment of insulin onto the magnetic nanoparticles, hence the achievement of Objective 1. The results from the CD and FTIR spectroscopy show that insulin’s conformation is unchanged before and after its attachment onto magnetic nanoparticles, hence the achievement of Objective 2. The general conclusion of the study is that the insulin’s conformation will not be affected by the attachment of it with magnetic nanoparticles.

▼ In this dissertation, we explored the fabrication of FePt nanoparticles and nano-islands with the face-centered tetragonal (fct, L10) phase prepared by both chemical synthesis routes and physical vapor deposition. Microstructure and magnetic properties characterizations were used to gain a fundamental understanding of the nano-structure formation and atomic ordering behavior and determine the possible applications in the next generation ultra-high density magnetic storage media. FePt nanoparticles prepared by thermal decomposition of iron pentacarbonyl [Fe(CO)5] have been widely investigated and by tuning the processing procedure monodispersed FePt nanoparticles with good assembly can be obtained. The as-made FePt nanoparticles are usually in the magnetically soft face-centered cubic (fcc) phase. To transformation to the fct phase, post-annealing at above 600°C is needed which, however, introduces undesirable agglomeration and sintering. To address this problem, we used three different fabrication processes which are discussed below. In the first fabrication experiment, the FePt nanoparticles were fabricated by a novel environmental friendly method involving crystalline saline complex hexaaquairon (II) hexachloroplatinate ([Fe(H2O)6]PtCl 6) with a special layered structure. Then the precursor was ball milled with NaCl and annealed at temperatures above 400°C under a reducing atmosphere of forming gas (95% Ar and 5% H2) FePt nanoparticles were obtained after washing away NaCl with deionized water. This method avoids the use of the very poisonous Fe(CO)5 and other organic solvents such as oleylamine and oleic acid. Instead, environmentally friendly NaCl and water were used. The size of FePt nanoparticles was controlled by varying the proportion of precursor and NaCl (from 10mg/20g to 50mg/20g). Particles with size in the range of 6.2–13.2 nm were obtained. All the nanoparticles annealed above 400°C are in the highly ordered fct phase with a coercivity range of 4.7 kOe to 10.7 kOe. Compared with reported high annealing temperatures above 600°C, this fabrication process led to a significantly decreased temperature to achieve the L10 phase FePt by 200°C. A qualitative model was set up to explain the surprising low L10 phase achievement temperature and the influence of annealing temperature on the microstructure and magnetic properties was investigated. Although FePt nanoparticles with high coercivity and small size were successfully obtained by the first fabrication method, agglomeration happened during the washing procedure due to the large inter-particle magnetostatic force caused by their high magnetization. To avoid this agglomeration, exfoliated graphene was introduced in the second preparation method to keep the nanoparticles separated. Different from the traditional solvent-phase reaction to disperse FePt nanoparticles onto the exfoliated graphene, a novel solid-phase reaction was used in this dissertation involving the layered precursor [Fe(H2 O)6]PtCl6 molecule. The [Fe(H2O) 6]PtCl6 water solution was… Advisors/Committee Members: Hadjipanayis, George C..

▼ One of the developing areas in silicon chemistry is in small silicon particles, primarily the nanoparticles regime. When on the 'nano' scale, silicon possesses very different properties and characteristics from bulk silicon. These properties include novel optical and electronic properties that are size dependent. Semiconductor nanoparticles possess a unique bright photoluminescence when in the nanoparticle regime. The photoluminescence in the nanoparticle regime answers the problem of inefficient emissions, which have previously been a problem in bulk silicon, for use in solar cells. Nanoparticle silicon (np-Si) is also biocompatible, allowing for the use in various biological applications including biological tracers, biosensors, delivery of medicine, as well as many others. Although np-Si is widely used, its surface structure still remains largely debated. The surface structure of np-Si is of critical importance as it affects the reactivity of the sample as well as the properties the samples possess. Relative to other silicon samples, np-Si lends itself to be studied by solid state NMR due to its higher surface area, although other types of silicon samples have been studied to some degree in this dissertation project. The surface structure and adjacent interior of np-Si, obtained as commercially available silicon nanopowder, were studied in this project using multinuclear, solid-state NMR spectroscopy. The results are consistent with an overall picture in which the bulk of the np-Si interior consists of highly ordered ('crystalline') silicon atoms, each bound tetrahedrally to four other silicon atoms. From a combination of 1H and 29Si magic-angle-spinning (MAS) NMR results and quantum mechanical 29Si chemical shift calculations, silicon atoms on the surface of 'as-received' np-Si were found to exist in a variety of chemical structures, including primarily structures of the types (Si-O-)n(Si-)3-nSi-H (with n = 1 - 3) and (Si-O-)2Si(H)OH, where Si stands for a surface silicon atom and Si represents another silicon atom that is attached to Si by either a Si-Si bond or a Si-O-Si linkage. The relative populations of each of these structures can be modified by chemical treatment, including with O2 gas at elevated temperature. A deliberately oxidized sample displays an increased population of (Si-O-)3Si-H, as well as (Si-O-)3SiOH sites. Considerable heterogeneity of some types of surface structures was observed. A comparison of 29Si and 1H MAS experiments provide strong evidence for a modest population of silanol (Si-OH) moieties, along with the dominant Si-H sites, on the surface of 'unmodified' np-Si; the former moieties are enhanced by deliberate oxidation of the sample. Dipolar-dephasing experiments provide further evidence of Si-H sites on the surface. Advisors/Committee Members: Maciel, Gary E.

▼ Continuous microfluidic technology has proven to be a potential competitor with established batch systems for facilitating chemical synthesis and purification, and more amenable to miniaturization, integration, and automation. Nevertheless, combining synthesis, purification and analysis remains a challenge due to the lack of development in efficient continuous flow purification techniques. An emerging continuous-flow purification technique is magnetophoresis, which utilizes surface-functionalized magnetic particles to selectively capture target molecules through specific binding, followed by manipulating the migration of particles through external magnetic force. This dissertation explores the synthesis of monodisperse core-shell functionalized magnetic nanoparticles composed of a single-core structure, and their application in magnetic manipulation for capture and isolation of targets in the continuous flow. First, single-cored magnetic nanoparticles with surface functionalities were prepared by coating functional triethoxysilanes onto iron oxide nanoparticles. The morphology, size, and colloidal stability of the resulting functionalized magnetic nanoparticles can be predicted and controlled. Second, a microfluidic device was fabricated from poly(dimethylsiloxane)(PDMS), consisting of two major components, a mixer and a separator (a diagram shown below). In the mixer, target molecules were captured by functionalized magnetic nanoparticles in a T-shape microchannel. Then the magnetic bead-target complex is directed into the separator, where the captured target molecules are magnetically steered out of the matrix while passing through a laminar co-flow profile. For proof of concept, we used a mixture of toluidine blue O (TBO) and sodium fluorescein as a model target and nontarget, respectively, and carboxyl functionalized magnetic beads as a receptor, leading to the selective complexation of TBO and magnetic beads via electrostatic binding. The device allowed for complete separation of the target from the nontarget molecules with high separation selectivity and efficiency as well as excellent reliability and flexibility.

▼ Magnetic patterning plays a paramount important role in information technology, which includes magnetic patterned media, magnetic random access memory and magnetic domain wall devices. Magnetic nanoparticles, especially iron oxide nanoparticles in patterning, have gained considerable attention not only due to their applications in data storage, biosensors, and contrast agents, but they show tunable magnetic properties based on different size, shape and phase. Both top-down lithographic approaches and bottom-up self-assembly procedures can be used in nanostructure patterning to achieve high packing density. The conventional lithography methods need to create a pattern in a resist layer and then transfer to a magnetic film. In terms of lithography methods, optical lithography is a typical method but limited in resolution because of the wavelength of light and the system numerical aperture. Interference lithography can produce high resolution pattern in a large scale for disk. However, the pattern size is limited to diameter of laser beam, which is hard to achieve the resolution required for discrete bit recording. Electron beam lithography can produce patterns with different size and shape. But this method is expensive and slow because it is a serial writing process. High resolution and large-scale patterns can be produced by x-ray lithography in a single exposure, however, such areas require high intensity x-ray sources. Self-assembly methods include natural self-ordered material patterning and guided self-assembly patterning. Self-ordered structures in nature can produce the ordered-array mask to reach the small dimension of patterns, however, the array is up to micrometer scale, and does not have circular symmetry. Guided self-assembly can be used to create long range ordering by using physical method, where a topographical pattern is created in a substrate, and chemical method, where the surface chemistry is selectively modified to produce nanostructures in some areas. However, both of physical and chemistry modifying methods may have problems on line edge roughness and individual bit alignment, which remain to be investigated.; An ideal method to produce magnetic patterns should be large scale, rapid, low cost, low intensity and fitting different devices well. High energy laser is considered to be a high throughput tool to cause rapid temperature rise and oxidize the materials. The laser frequency can be tuned to match the absorbance spectrum of targeted material, so that the selectivity of magnetic patterning could be possible by selectively oxidizing metal ions. The use of excimer laser in magnetic patterning has been explored in conventional lithography to create mask, which is slow and expensive.; This research reports the feasibility study of using high power excimer laser to oxidize iron ion to produce magnetic pattern in porous matrix, where a focused laser beam will heat up and cause oxidation of metal ion. This method combines physical lithography method to produce magnetic patterns rapidly and chemical…

▼ The use of nanomaterials for biomedical applications is an emerging and important field. This is particularly true of advancements in targeted and controlled drug delivery, which offer several important improvements over traditional drug administration. The clinical efficacy of small-molecule therapeutics is currently limited by many factors, including: poor solubility, inefficient cellular uptake, overly rapid renal clearance and an inability to target only desired locations such as diseased tissues. The use of nanocarriers for drug delivery may greatly improve the efficacy over traditional therapeutics by lowering the total dosage, limiting the exposure to affected areas only, and giving greater temporal control over drug elution. These materials often make use of both organic and inorganic components, exploiting the unique and useful properties of each constituent to achieve novel, synergistic functions. This dissertation presents a study of nanocomposites comprising the three most important materials in this field: titania, iron oxides and polypyrrole. Titania is a strong photocatalyst, iron oxides provide useful responses to applied magnetic fields, and polypyrrole is a polymer with unique electrochemical properties. Studies in this dissertation were aimed at combining these three materials to create a novel structure that is responsive towards light, magnetic fields and electrical stimulation to serve as an enabling platform for the loading and release of biologically interesting compounds. These nanomaterials have been paired with amino acids L-lysine and L-glutamic acid, two organic molecules of interest due to their ability to bind to DNA and proteins, and to form prodrugs that exhibit enhanced performance compared to traditionally administered medicines. Two model compounds have been loaded and released on these carriers: Ketoprofen, an important anti-inflammatory that is traditionally hindered by its limited cellular uptake levels; and fluorescein isothiocyanate, a fluorescent dye molecule that is a common tool used in this field for nanocarrier location and easy visualisation of release-related kinetics. First, an investigation into the effect of pH on the binding of amino acids to titania, iron oxide and polypyrrole is presented with a view towards optimising the functionalised material for subsequent loading and release of the model drugs (in this case, amine-reactive molecules). The release mechanism of photo-activated TiO2 is studied in detail with a particular focus on the competition between the cleavage of bonds versus organic degradation on the catalyst’s surface. Both mechanisms are currently reported in literature and studies were aimed at identifying the more dominant pathway in the system developed alongside understanding the crucial role of…
