Is Thermocapillary Enough For Droplet Actuation?

Abstract

In case of immiscible liquids, when a droplet is released from a certain height, based on the surface shape at the air- liquid interface, the droplet can migrate toward or away from the heated surface. This can be explained based on surface tension gradient which is caused by thermal gradient at the interface (thermocapillary effect). Accordingly, a novel thermally-actuated platform is proposed, which is capable of exact droplet manipulation. An array of heaters is embedded on a silicon wafer, by which thermal maps can be applied on the platform, and droplets can be transported to desired locations without evaporation or contamination.
