Chemical channels are formed by lyophilic stripes within a lyophobic environment on a topologically plain surface. We theoretically analyze the energetic properties and spatial morphologies of a droplet in the vicinity of a Y-junction in a capillary model in quasistationary approximation with special respect to the so-called disjoining pressure. The origin of the disjoining pressure are long range intermolecular dispersion forces which have to be taken into account when scaling down the system from the micro to the nano range. Understanding the dynamics on microfluidic devices and finding design criteria for a miniaturization of the latter down to the nano range is the motivation of our work.
