FIG. 1.

Electrocoalescence-based serial dilution microfluidic device. (a) Schematic of the electrocoalescence based dilution process, showing the drop generation, electrocoalescence, and the serially diluted droplets (left). Because of electrocoalescence, the drops merge causing a two-way transfer of fluid (right). (b) The three-dimensional model showing the detailed design of the device. Widths of main channel, bypass, electrode channel, and trap are 145, 100, 50, and 270 μm, respectively. Channel heights are uniformly 200 μm in the device.
