  1. Wetting and Drying: Physics and Pattern Formation


Digital microfluidics provides precise control of a single microdroplet, producing more opportunities for bio-molecule studies, chemical reaction and optofluidics applications. By manipulating the surface of droplets, light can be focused, scattered, or reflected toward different positions. We build a model of electro-responsive optical microfluidic system, operated based on the electrowetting mechanism, which can split or push droplets moving within a microwell. The initial close state and operated open state in a single microwell displays the color of a dye oil droplet and the substrate, respectively, represented as the dark and bright pixel in the display board. Our results indicate that the microdroplets interface could be successfully deformed and moved towards different directions within a short period of time.
