Electrochemical immobilization of enzymes. Part V. Microelectrodes for the detection of glucose based on glucose oxidase immobilized in a poly(phenol) film

Abstract

The adsorption of glucose oxidase at a platinum electrode followed by immobilization in an electrochemically polymerized phenol film was found to be a reproducible method for the fabrication of enzyme microelectrodes responsive to glucose. The observed responses were comparable to those predicted on the basis of monolayer coverage of the enzyme. The electrodes were found to be stable for more than 40 d on storage at 4 °C.
