Several micro- and nanomanipulation techniques have emerged in recent decades thanks to advances in micro- and nanofabrication. For instance, the atomic force microscope (AFM) uses a nano-sized tip to image, push, pull, cut, and indent biological material in air, liquid, or vacuum. Using micro- and nanofabrication techniques, scientists can make ma

Critical to the development of lab-on-a-chip (LOC) devices is the ability to accurately manipulate microparticles and cells within microfluidic volumes. In real fluid samples, the analyte of interest usually coexists in low concentration amongst a myriad of other constituents, resulting in the need for pre-analytical preparation procedures. Consequently, much research attention has been directed towards concentrating and/or isolating the analyte of interest from the other constituents within microfluidic volumes. The central theme of this thesis is the ultrasonic manipulation of particles and cells within microfluidic systems. Acoustically driven mechanisms for particle and cell manipulation are particularly advantageous as these techniques generally exhibit high throughput, have negligible physiological effects on cells, and are highly portable. Comprising both experimental and theoretical investigations, the studies presented herein focus on the selective concentration and isolation of one particle type from another. Both bulk acoustic wave (BAW) and surface acoustic wave (SAW) devices provide physical platforms for the microfluidic manipulation techniques. Specifically, three related studies are included: (1) selective particle concentration and isolation within a droplet, (2) particle and cell clustering at air-liquid interfaces, and (3) selective particle trapping using oscillating bubbles. These studies illustrate the intricate interplay of physics between fluid drag and acoustic forcing on the particles, where parameters such as frequency, particle size and device geometry have been exploited to achieve such results. Furthermore, these findings demonstrate the possibility and benefits of using acoustic actuation methods as a platform for microfluidic LOC devices.

The manipulation of cells and microparticles within microfluidic systems using external forces is valuable for many microscale analytical and bioanalytical applications. Acoustofluidics is the ultrasound-based external forcing of microparticles with microfluidic systems. It has gained much interest because it allows for the simple label-free separation of microparticles based on their mechanical properties without affecting the microparticles themselves. Microscale Acoustofluidics provides an introduction to the field providing the background to the fundamental physics including chapters on governing equations in microfluidics and perturbation theory and ultrasound resonances, acoustic radiation force on small particles, continuum mechanics for ultrasonic particle manipulation, and piezoelectricity and application to the excitation of acoustic fields for ultrasonic particle manipulation. The book also provides information on the design and characterization of ultrasonic particle manipulation devices as well as applications in acoustic trapping and immunoassays. Written by leading experts in the field, the book will appeal to postgraduate students and researchers interested in microfluidics and lab-on-a-chip applications.
