The immobilized enzyme is necessary for the development of enzyme fuel cells (EFCs) which can be applied to power source of implantable devices. The main issue to be solved is the low generation of electrical power by enzyme electrode due to several problems. One of them is the possible attachment of active site of enzyme onto support materials during immobilization of enzymes, which may decrease the chances to react between substrates and enzymes, thereby decreasing power density. Here, active site of enzyme (glucose oxidase) was masked by glucose or gluconic acid to protect active site from attachment on support material during immobilization on multiwall carbon nanotube. It was found that electric power density was increased by enzyme electrode prepared by this novel immobilization method.
