High Speed Acoustophoresis for Multiphase Micron-Sized Particle Assembly
Acoustophoresis assembly is a non-contact assembly method characterized by its ability to assemble micron particles in 2D and 3D mm-scale patterns and its material agonism. In this method, acoustic standing wave pressure gradients interact with the particles to generate the acoustic radiation …

Separation and Further Characterization of Hematopoietic Cell Populations Based on Phenotypic and Biophysical Properties
… numbers. Furthermore, a novel micro-chip based acoustophoresis technique was invesigated (paper IV) for removal of platelets from PBPC products and was found to efficiently deplete PBPC samples of intact platelets, whilst preserving the target leukocyte fraction, cell viability and progenitor …

Formation Process of Acoustophoretic Patterns
… the pattern geometries that can be made using acoustophoresis, the effort is largely still in the proof of concept stage and the final pattern quality is often only evaluated qualitatively. There is also a need to measure the pattern formation process so that the inherent design tradeoffs can …

Numerical Study of Acoustophoretic and Thermophoretic Aggregation of Micro- and Nano-Sized Particles
… few studies have been conducted to optimise the acoustophoresis or thermophoresis device design. Therefore, this dissertation aims to improve the efficiency and accuracy of the micro/nanoparticle aggregation devices through numerical modelling using the finite element method. This research first …

Acoustofluidic Innovations for Cellular Processing On-Chip
… undergo positive magnetophoresis and negative acoustophoresis in water. Further, I show that these particles can be functionalized with biomolecules via chemical modification by linking a biotin group to the surface-accessible amine groups on the particles using carbodiimide chemistry. These …

Soft Self-assembly and Densest Packings in Colloidal Models
… for investigating the limits of particle acoustophoresis. To extend our results, we use our theoretical model to estimate, for the first time, the minimum pressure amplitude necessary to concentrate nanoparticles of any composition. Finally, to overcome the limitations of focusing of …
