Glucose Oxidase-Modified SnO2 Electrode as Electrochemical Glucose Sensor

Abstract

Abstract Glucose oxidase was chemically immobilized on an SnO2 electrode via 1) 2,4,6-trichloro-1,3,5-triazine, 2) 3-aminopropyltriethoxysilane and glutaraldehyde, or 3) crosslinkage of enzyme molecules by glutaraldehyde. These enzyme-immobilized electrodes were compared regarding the performance as amperometric glucose sensors.
