Abstract

Electrochemically induced free radical polymerization of methacrylic acid was preliminarily investigated. Based on the electrochemical reduction of persulfate anion in phosphate buffer (pH 7.0) solution,the free radical polymerization of methacrylic acid was initiated to generate an ultrathin and biocompatible hydrogel layer on the gold electrode. At the meantime,glucose oxidase could be immobilized within the hydrogel film in the polymerization process. The resulting biosensor displayed an attractive performance.
