Abstract

Droplets are a versatile platform for performing chemical reactions, detection and compartmentalization. When a droplet is in a two-phase device droplet-based processes can be performed without the need for fluid handling, with small reaction volumes reducing the need to perform separate mixing steps and reducing reaction times. While techniques exist to produce continuous trains of water-in-oil droplets, it has been difficult to produce individual droplets on-demand, a prerequisite for more complex programmable microfluidic devices. Here we present a novel method for integrating a pressure source on-chip, producing picoliter scale water-in-oil droplets on-demand using surface acoustic waves.
