Abstract

We describe a simple photolithographic method for patterning a porous membrane to create well-defined polymer walls to improve the printability of a colorimetric sensor array. The resulting array demonstrated highly selective detection of 2,4,6-trinitrotoluene (TNT) vapour and other nitroaromatic compounds.
