Acoustic focusing of microparticles in two-phase systems - Towards cell enrichment or medium exchange in droplets

Fornell, Anna LU ; Jonsson, Håkan N.; Nilsson, Johan and Tenje, Maria LU (2015) 19th International Conference on Miniaturized Systems for Chemistry and Life Sciences, MicroTAS 2015 p.1026-1028
Abstract

We present a method to first laterally position microparticles inside droplets by acoustic forces and then split the droplet into three daughter droplets to achieve a 2+fold enrichment of microparticles inside the center droplet. We show that acoustic forces can be applied to both manipulate polystyrene beads (5 μm) and red blood cells inside droplets. The presented technology opens up for development of droplet operations used for medium exchange and particle concentration in droplet-based cell assays.
