What is microfluidics?
Microfluidic devices are used in a variety of research, industrial and therapeutic applications. These devices take advantage of the physics at small length scales, where surface tension and interfacial effects dominate over more familiar forces, such as gravity. Most importantly, by creating physical structures or force fields (electrical, magnetic or acoustic) with dimensions on the order of microns, individual cells and particles can be manipulated and analysed for rapid and low-volume cell studies and diagnostics.
What is SAW?
Surface acoustic wave (SAW) actuation is a developing method for the manipulation of particles and cells in microfluidic systems. I have developed systems using SAW for particle and cell concentration, controlled release, droplet production and encapsulation, high-sensitivity sorting, atomization and single-cell analysis. SAW is especially applicable to microfluidic systems given its large (and biocompatible) forces with acoustic wavelengths (3-300 µm) on the same size scale as cells and microfluidic systems.
