▼ Particles of nanometer- and micrometer-size, including diverse types of aerosol, dusts, and material powders, pose significant influence on environment, climate, human health, and material properties. Our understanding towards these particles and materials is mainly established from bulk samples and from particles deposited on substrates or dispersed in liquid solutions. However, fundamental properties and interactions of single particles cannot be fully resolved by characterizing bulk materials or deposited particles. Pristine physicochemical properties and rudimentary gas-particle interactions can only be investigated from single particles in their native states. The goal of this dissertation is to study single particles in gaseous environment with minimum external interferences. Diverse optical trapping (OT) methods for trapping and manipulating single airborne particles were explored and summarized. These configurations are categorized into radiation-pressure traps, photophoretic traps, and universal optical traps (UOT), according to particles absorbance. The UOT configurations are able to trap and manipulate a wide variety of single particles, including transparent and absorbing, spherical and irregular, inorganic and biological particles. Four key aspects of these OTs, simplicity, robustness, flexibility, and efficiency, are brought up to evaluate OT capabilities, providing a guidance to select the optimal optical configuration for specific applications. With single particles stably trapped, optical manipulations and characterizations can therefore be interrogated. Single-particle manipulations in air from one-dimension to three-dimension are reviewed; pulling and pushing single optically trapped particles along a Gaussian laser beam were explored and explained. Cavity ringdown spectroscopy is integrated with OTs to measure the light extinctions of trapped particles. Microscopic imaging and Raman systems are combined with the OT to examine the trapped particles. A few application examples of this optical trapping-Raman spectroscopy system are demonstrated, including online characterizing carbon particles, effectively bleaching fluorescence in dye-doped polymer microspheres, acquiring clean Raman spectra of single biological particles, and monitoring chemical reactions in single biological particles. Optical trapping, associated with advanced laser spectroscopic techniques, offer a great flexibility for trapping, manipulating, characterizing, and monitoring single particles in air.

▼ Optical tweezers have been an important tool in biology and physics for studying single molecules and colloidal systems. Most of current optical tweezers are built with microscope objectives, which are: i) expensive, ii) bulky and hard to integrate, iii) sensitive to environmental fluctuations, iv) limited in terms of working distances from the substrate, and v) rigid with the requirements on the substrate (transparent substrate made with glass and with a fixed thickness). These limitations of objective-based optical tweezers prevent them from being miniaturized. Fiber optical tweezers can provide a solution for cost reduction and miniaturization, and these optical tweezers can be potentially used in microfluidic systems. However, the existing fiber optical tweezers have the following limitations: i) low trapping efficiency due to weakly focused beams, ii) lack of the ability to control the positions of multiple particles simultaneously, and iii) limited functionalities. The overall objective of this dissertation work is to further the fundamental understanding of fiber optical tweezers through experimental study and modeling, and to develop novel fiber optical tweezers systems to enhance the capability and functionalities of fiber optical tweezers as microscale and nanoscale manipulators/sensors. The contributions of this dissertation work are summarized as follows: i) An enhanced understanding of the inclined dual-fiber optical tweezers (DFOTs) system has been achieved. Stable three dimensional (3D) optical trapping of a single micron-sized particle has been experimentally demonstrated. This is the first time that the trapping efficiency has been calibrated and the stiffness of the trap has been obtained in the experiments, which has been carried out by using two methods: the drag force method and power spectrum analysis. Such calibration enables the system to be used as a picoNewton-level force sensor in addition to a particle manipulator. The influence of system parameters on the trapping performance has been carefully investigated through both experimental and numerical studies. ii) Multiple traps have been created and carefully studied with the inclined DFOTs for the first time. Three traps, one 3D trap and two 2D traps, have been experimentally created at different vertical levels with adjustable separations and positions. iii) Multiple functionalities have been achieved and studied for the first time with the inclined DFOTs. Particle separation, grouping, stacking, rod alignment, rod rotation, and optical binding have been experimentally demonstrated. The multiple functionalities allow the inclined DFOTs to find applications in the study of interaction forces in colloidal systems as well as parallel particle manipulation in drug delivery systems. iv) Far-field superfocusing effect has been investigated and successfully demonstrated with a fiber-based surface plasmonic (SP) lens for the first time. A planar SP lens with a set of concentric nanoscale rings on a fiber endface has been developed. For the first… Advisors/Committee Members: Yu, Miao (advisor).

▼ The invention of the laser in 1960 opened the door for a myriad of studies on the interactions between light and matter. Eventually it was shown that highly focused laser beams could be used to con fine and manipulate matter in a controlled way, and these instruments were known as optical traps. However, challenges remain as there is a delicate balance between object size, precision of control, laser power, and temperature that must be satisfied. In Part I of this dissertation, I describe the development of two optical trapping instruments which substantially extend the allowed parameter ranges. Both instruments utilize a standing wave optical field to generate strong optical gradient forces while minimizing the optical scattering forces, thus dramatically improving trapping efficiency. One instrument uses a cylinder lens to extend the trapping region into a line focus, rather than a point focus, thereby confining objects to 1D motion. By translation of the cylinder lens, lateral scattering forces can be generated to transport objects along the 1D trapping volume, and these scattering forces can be controlled independently of the optical gradient forces. The second instrument uses a collimated beam to generate wide, planar trapping regions which can con fine nanoparticles to 2D motion. In Part II, I use these instruments to provide the first quantitative measurements of the optical binding interaction between nanoparticles. I show that the optical binding force can be over 20 times stronger than the optical gradient force generated in typical optical traps, and I map out the 2D optical binding energy landscape between a pair of gold nanoparticles. I show how this ultra-strong optical binding leads to the self-assembly of multiple nanoparticles into larger contactless clusters of well de ned geometry. I nally show that these clusters have a geometry dependent coupling to the external optical field.

▼ In a time when microorganisms are controlling the world, research in biology is more relevant than ever and this requires some powerful instruments. Optical tweezers use a focused laser beam to manipulate and probe objects on the nano- and microscale. This allows for the exploration of a miniature world at the border between biology, chemistry and physics. New methods for biophysical and physicochemical measurements are continuously being developed and at Umeå University there is a need for a new system that combines several of these methods. This would truly be the new Swiss army knife of biophysical and biomechanical research, extending their reach in the world of optical tweezing. My ambition with this project is to design and construct a robust system that incorporates optical trapping with high-precision force measurements and Raman spectroscopy, as well as introducing the possibility of generating multiple traps by using a spatial light modulator (SLM). The proposed design incorporates four different lasers and a novel combination of signal detection techniques. To allow for precise control of the systems components and laser beams, I designed and constructed motorized opto-mechanical components. These are controlled by an in-house developed software that handles data processing and signal analysis, while also providing a user interface for the system. The components include, motorized beam blockers and optical attenuators, which were developed using commonly available 3D printing techniques and electronic controllers. By designing the system from scratch, I could eliminate the known weaknesses of conventional systems and allow for a modular design where components can be added easily. The system is divided into two parts, a laser breadboard and a main breadboard. The former contains all the equipment needed to generate and control the laser beams, which are then coupled through optical fibers to the latter. This contains the components needed to move the optical trap inside the sample chamber, while performing measurements and providing user feedback. Construction and testing was done for one sub-system at a time, while the lack of time required a postponement for the implementation of Raman and SLM. The system performance was verified through Allan variance stability tests and the results were compared with other optical tweezers setups. The results show that the system follows the thermal limit for averaging times (τ) up to ~1 s when disturbances had been eliminated, which is similar to other systems. However, we could also show a decrease in variance all the way to τ = 2000 s, which is exceptionally good and not found in conventional systems. The force-resolution was determined to be on the order of femtonewtons, which is also exceptionally good. Thus, I conclude that this optical tweezers setup could lie as a solid foundation for future development and research in biological science at Umeå University for years to come.

▼ The ability to control and manipulate the world around us is human nature. Humans and our ancestors have used tools for millions of years. Only in recent years have we been able to control objects at such small levels. In order to understand the world around us it is frequently necessary to interact with the biological world. Optical trapping and manipulation offer a non-invasive way to move, sort and interact with particles and cells to see how they react to the world around them. Optical tweezers are ideal in their abilities but they require large, non-portable, and expensive setups limiting how and where we can use them. A cheap portable platform is required in order to have optical manipulation reach its full potential. On-chip technology offers a great solution to this challenge. We focused on the Liquid-Core Anti-Resonant Reflecting Optical Waveguide (liquid-core ARROW) for our work. The ARROW is an ideal platform, which has anti-resonant layers which allow light to be guided in liquids, allowing for particles to easily be manipulated. It is manufactured using standard silicon manufacturing techniques making it easy to produce. The planner design makes it easy to integrate with other technologies. Initially I worked to improve the ARROW chip by reducing the intersection losses and by reducing the fluorescence and background on the ARROW chip. The ARROW chip has already been used to trap and push particles along its channel but here I introduce several new methods of particle trapping and manipulation on the ARROW chip. Traditional two beam traps use two counter propagating beams. A trapping scheme that uses two orthogonal beams which counter to first instinct allow for trapping at their intersection is introduced. This scheme is thoroughly predicted and analyzed using realistic conditions. Simulations of this method were done using a program which looks at both the fluidics and optical sources to model complex situations. These simulations were also used to model and predict a sorting method which combines fluid flow with a single optical source to automatically sort dielectric particles by size in waveguide networks. These simulations were shown to be accurate when repeated on-chip. Lastly I introduce a particle trapping technique that uses Multimode Interference(MMI) patterns in order to trap multiple particles at once. The location of the traps can be adjusted as can the number of trapping location by changing the input wavelength. By changing the wavelength back and forth between two values this MMI can be used to pass a particle down the channel like a conveyor belt.

▼ The ability to trap and control single particles in free solution has led to major advances in science and engineering. Common methods for particle trapping and manipulation often rely on optical, magnetic, acoustic, or electric forces. However, the vast majority of these methods critically depend on the target particle possessing specific physical properties such as index of refraction or surface charge. In this research, we have designed and built a Stokes trap, which allows for the manipulation and control of an arbitrary number of arbitrary type particles using only fluid flow. In this way, we have effectively constructed a `smart microfluidic device' by coupling feedback control with microfluidics, thereby enabling new routes for the fluidic-directed assembly of particles. This work is comprised of three distinct but interrelated efforts towards the precision trapping and manipulation of multiple particles using fluid flow. In the first project, the control algorithm for a microfluidic process is extensively studied for confining a single particle in solution. Here, we study the response of trapped particles actuated using a combination of proportional, integral, and derivative controllers (PID control), which extends beyond our prior work where we utilized a simple proportional controller for 2-D manipulation of particles in free solution. We investigate the effect of controller gains, flow rate, and feedback response times on the robustness of trapping, using a combination of simulation and experimental studies. In the second project, we present the development and application of the Stokes Trap, which is a multiplexed microfluidic method for arbitrary manipulation of an arbitrary number of particles in solution. We demonstrate simultaneous manipulation of two particles in a simple microfluidic device, and also achieve fluidic directed assembly of multiple particles in solution. In the third project, the Stokes trap is used to implement and experimentally demonstrate trajectory control using fluidic trapping, wherein particles are controlled by a path-following framework that improves the precision and the speed of manipulation of particles along arbitrary paths. An extended Kalman filter is also implemented, which effectively reduces the offset due to unmodeled phenomena during particle trapping. Finally, these techniques are leveraged to demonstrate the direct determination of solvent-mediated hydrodynamic interactions (HI) between two freely suspended colloidal particles in flow. From a broad perspective, this work provides a robust framework for studying fundamental interactions between particles or for guiding the directed assembly of materials.

La pression de radiation acoustique est la force moyenne qu'une onde peut exercer sur un obstacle. Initialement, la faible manifestation de cette force ne suggérait pas d'applications potentielles. Néanmoins, avec l'avènement de sources acoustiques de haute puissance, il a rapidement été envisagé de manipuler de petits objets à distance par pression de radiation. Depuis, c'est via l'excitation d'ondes stationnaires dans des cavités que cette méthodologie connait son essor. Parallèlement, la pression de radiation de la lumière a rapidement permis de piéger et de manipuler des petits objets. Grâce à un laser fortement focalisé, la pince optique a donné une grande flexibilité aux techniques de manipulation sans contact et est devenue un outil fondamental pour de nombreuses disciplines scientifiques. Cependant, les faibles forces développées, les importantes intensités lumineuses requises et la petite taille des objets sont d'importantes limites tout particulièrement pour leur application en biologie.A l'heure actuelle, il n'existe pas l'équivalent de la pince optique en acoustique utilisant un unique faisceau. Le travail présenté donne un ensemble d'éléments théoriques et expérimentaux profitables pour la compréhension de la pression de radiation en acoustique et le dimensionnement d'une pince acoustique utilisant un unique faisceau ultrasonore : le vortex acoustique. Ce travail esquisse l'ébauche d'une nouvelle méthode de manipulation sans contact donnant une véritable dextérité de préhension. Les faibles intensités nécessaires associées aux larges forces développées sauront se montrer attractives pour imaginer un large panel de nouvelles applications scientifiques.

As an acoustic wave impinges an obstacle, a mean force is exerted on its surface. This so-called radiation pressure arises from the non linear interaction between the wave and the object.The early history of this force did not suggest any application of such a feeble effect. Nevertheless, as technological advances improved the prospects of new powerful sound sources, it was rapidly considered to use the acoustic radiation pressure as a mean of non-contact manipulation of small objects. Ever since, standing wave schemes excited in cavities has been the preferred strategy that is becoming considerably popular.In the same time, the radiation pressure of light was also recognised to trap and manipulate very small objects. Using a single focused laser beam, optical tweezers brought a great dexterity to non contact manipulation techniques and rapidly grew to become a fundamental tool in many scientific fields. However, the minuteness of the force, the high intensities required and the smallness of trappable objects are well-known limitations in particular for biological applications.Although optics and acoustics have shown many similarities, an acoustical analogue to optical tweezers using a single beam is yet to be demonstrated. Theoretical and experimental efforts are presented here and shed light on the underpinning mechanisms of single-beam acoustical…

▼ Integration and miniaturisation in electronics has undoubtedly revolutionised the modern world. In biotechnology, emerging lab-on-a-chip (LOC) methodologies promise all-integrated laboratory processes, to perform complete biochemical or medical synthesis and analysis encapsulated on small microchips. The integration of electrical, optical and physical sensors, and control devices, with fluid handling, is creating a new class of functional chip-based systems. Scaled down onto a chip, reagent and sample consumption is reduced, point-of-care or in-the-field usage is enabled through portability, costs are reduced, automation increases the ease of use, and favourable scaling laws can be exploited, such as improved fluid control. The capacity to manipulate single cells on-chip has applications across the life sciences, in biotechnology, pharmacology, medical diagnostics and drug discovery. This thesis explores multiple applications of optical manipulation within microfluidic chips. Used in combination with microfluidic systems, optics adds powerful functionalities to emerging LOC technologies. These include particle management such as immobilising, sorting, concentrating, and transportation of cell-sized objects, along with sensing, spectroscopic interrogation, and cell treatment. The work in this thesis brings several key applications of optical techniques for manipulating and porating cell-sized microscopic particles to within microfluidic chips. The fields of optical trapping, optical tweezers and optical sorting are reviewed in the context of lab-on-a-chip application, and the physics of the laminar fluid flow exhibited at this size scale is detailed. Microfluidic chip fabrication methods are presented, including a robust method for the introduction of optical fibres for laser beam delivery, which is demonstrated in a dual-beam optical trap chip and in optical chromatography using photonic crystal fibre. The use of a total internal reflection microscope objective lens is utilised in a novel demonstration of propelling particles within fluid flow. The size and refractive index dependency is modelled and experimentally characterised, before presenting continuous passive optical sorting of microparticles based on these intrinsic optical properties, in a microfluidic chip. Finally, a microfluidic system is utilised in the delivery of mammalian cells to a focused femtosecond laser beam for continuous, high throughput photoporation. The optical injection efficiency of inserting a fluorescent dye is determined and the cell viability is evaluated. This could form the basis for ultra-high throughput, efficient transfection of cells, with the advantages of single cell treatment and unrivalled viability using this optical technique.

▼ The necessity of micromanipulation to separate, focus and transport discrete objects on a microscopic scale has emerged in recent years in areas from assisted fertilization to precision machining. This work explores the manipulation of microparticles suspended in viscous streaming flow. Streaming is a steady large-scale circulatory flow generated by the nonlinear interaction of the primary oscillatory motion. The first part of the study focuses on particle transport and trapping in the streaming flow generated by a single oscillating cylinder. The streaming flow is obtained by asymptotic expansion from previous work and the resulting velocity field is used to integrate the Maxey-Riley equation with the Saffman lift for the motion of an inertial spherical particle immersed in this flow. It is found that inertial particles spiral inward and become trapped inside one of the four streaming cells established by the cylinder oscillation, regardless of the particle size, density and flow Reynolds number. It is shown that the Faxen correction terms divert the particles from the fluid particle trajectories, and once diverted, the Saffman lift force is most responsible for effecting the inward motion and trapping. Results compare favorably with previous experiments.We extend this study to various arrangements of oscillating probes. High fidelity computations are used to simulate the flow field to capture particle transport. It is shown that, by controlling the sequence of starting and stopping the oscillation of individual probes, inertial particles can be transported in a predictable manner between trapping points. In order to reduce the considerable expense of generating the flow field, we also explore the use of steady Stokes flow to serve as an approximate surrogate for the flow between probes. The boundary conditions for this flow are obtained by matching with the inner Stokes layer solution in the asymptotic expansion for small amplitude. Finally, the practical characteristics of transport by streaming are discussed.Overall, this study reveals that viscous streaming is an effective mechanism with which to manipulate small particles. To the best of my knowledge, this work is the first to investigate inertial particle trapping and transport in viscous streaming theoretically and computationally.
