AB - We describe a universal mechanism for merging multiple aqueous microdroplets within a flowing stream consisting of an oil carrier phase. Our approach involves the use of both a pillar array acting as a passive merging element as well as integrated electrodes acting as an active merging element. The pillar array enables slowing down and trapping of the droplets via the drainage of the oil phase. This brings adjacent droplets into close proximity. At this point, a low electric field is applied to the electrodes which breaks up the thin oil film surrounding the droplets and subsequently results in merging. © 2009 CBMS.
