Simple Fabrication of a Highly Sensitive and Fast Glucose Biosensor Using Enzymes Immobilized in Mesocellular Carbon Foam

Abstract

Glucose oxidase immobilized in mesocellular carbon foam results in a highly sensitive and fast glucose biosensor. The structure of the mesocellular foam (see Figure), with a combination of mesopores containing the glucose oxidase (GOx) enzymes and micropores and transport channels, results in high enzyme loading and low mass-transfer limitations, producing higher catalytic activity and sensitivity than polymer-matrix-based GOx glucose sensors.
