Abstract

This paper presents a novel strategy for droplet microfluidics which enables the 2D manipulation of drops within microchannels without requiring any flow of the external phase. The key droplet operations such are production, transport, guiding, trapping and merging are implemented simply by modulating the shape of the top microchannel boundary. We demonstrate how to cover applications ranging from single droplet operations, common in digital microfluidics [1,2], to the high throughput available in classical flow-driven droplet microfluidics [3,4], all in simple and inexpensive devices.
