Abstract

A new, robust technique for preparing highly selective molecularly imprinted films (see Figure) is presented. Spin-coating is used to spread a pre-polymerization mixture on a substrate, which is subsequently cured with UV light. Important aspects of this technique include the use of a novel polymeric porogen dissolved in a low-volatility solvent to generate porous morphologies with enhanced binding capacities.
