Abstract

In this work, we demonstrate a microfluidic device capable of sorting picoliter water-in-oil droplets into multiple outlets using tunable standing surface acoustic wave (SSAW). Within the SSAW field, water-in-oil droplets experience an acoustic radiation force and are pushed towards the acoustic pressure node. As a result, by tuning the frequency of the SSAW excitation, the positions of the pressure nodes can be changed and droplets can be sorted to five different outlets. With its advantages of simplicity, controllability, versatility, non-invasiveness, and capability to be integrated with other on-chip components such as droplet manipulation and optical detection units, the technique presented here could be valuable for the development of droplet-based micro total analysis systems (μTAS).
