Abstract
An anti-microbial filter () for a micro-fluidic system () includes a silicon-based filter membrane () having holes () formed therein. The membrane () is formed on a substrate (). One side of the filter membrane () has an anti-microbial coating () between the holes () on the filter membrane () and the other side can include filter supports formed from a silicon substrate. A method for making the anti-microbial filter () includes forming a filter membrane () on a substrate (), forming holes () in the membrane () by providing a filter mask () and etching holes () through holes () in the mask (). Then portions of the substrate () are removed from the filter membrane () using a masking and etching process to expose the holes (). An anti-microbial coating is applied to the membrane () adjacent the holes ().
