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.
