Abstract

In this work, for the first time we demonstrate nanoscale (10-80 nL) droplet generation with open-loop volume control in electrowetting microchannels. Typical droplet generation and volume control methods in digital microfluidics require complex circuitry and signal processing [1,2]. Here we demonstrate a simple and reliable approach for droplet generation from a continuous electrowetting channel and volume control based on electrode size. Droplet volume was obtained by a simple image processing technique with a precision as high as 99.95%.
