Abstract

Advances in diagnostics, cell and stem cell technologies drive the development of application specific tools for cell and particle separation. Acoustic micro-particle separation offers a promising avenue for label-free, high recovery, cell and particle separation and isolation in tissue engineering and targeted drug delivery. In this paper, we present two methods of separating particles in a microfluidic channel. The first method uses custom-made micro-particles and by changing the acoustic contrast factor, the micro-particles shift from acoustic node to antinodes, compared to commercialised micro-particles. The second method relies on shifting the acoustic standing wave in a pattern called dynamic acoustic field. We demonstrate that both methods separate particles up to 100%.
