Photo-lithographically impregnated and molecularly imprinted polymer thin film for biosensor applications

Abstract

A voltammetric sensor for albuterol was investigated where we combined the techniques of microfabrication and molecular imprinting to construct on-chip devices using photoirradiation of cross-linkable polymers. Molecularly imprinted polymer was coated as a thin film onto the gold working electrode on chip and the analyte was directly quantified by differential pulse voltammetric measurements. © 2003 Elsevier B.V.
