Multiple patterned structures on a single substrate fabricated by elastomeric micro-molding techniques

Abstract

A method for patterning a material onto a substrate including the steps of: providing a micro-mold having a plurality of non-communicating independent channels and having a plurality of reservoirs for receiving a micro-molding fluid each of which reservoirs communicates with a channel, the micro-mold including an elastomeric master having a surface with a plurality of recesses therein and a substrate; introducing a micro-molding fluid into the micro-mold reservoirs filling said communicating channels; and solidifying the fluid in the micro-mold and removing the elastomeric master thereby generating a pattern of material on the substrate. The micro-mold is formed by contacting the surface of the elastomeric master with the substrate such that the recesses in the surface form the plurality of reservoirs and channels.
