Abstract

Manipulating droplets on an open surface promises an easier, more flexible, and more scalable platform of liquid control, than does microchannel-based fluidics. In this report, a surface-energy-trap-enabled magnetic droplet handling platform is introduced that is capable of comprehensive droplet manipulations, including droplet dispensing, transport, fusion, and particle extraction.
