Abstract
A microfluidic device for applying a liquid to a surface comprises a chamber for carrying the liquid, an aperture in the chamber for communicating liquid from the chamber to the surface via a conduit having outer sides of limited wetability to the liquid. This device provides a solution for confining liquids to defined areas of a surface without involving physical seals and additionally permits moving the device and confined liquid on the surface.
