Preparation of a magnetically switchable bioelectrocatalytic system employing cross-linked enzyme aggregates in magnetic mesocellular carbon foam

Abstract

Preparation of a Magnetically Switchable Bio-electrocatalytic System Employing Cross-Linked Enzyme Aggregates in Magnetic Mesocellular Carbon Foam Glucose oxidase (GOx) was immobilized in magnetic mesocellular carbon foam by cross-linking with glutaraldehyde. This material has been utilized to construct a magnetically switchable bio-electrocatalytic system in which the catalytic oxidation of glucose could be switched on and off by the positioning of an external magnet near and away from the electrode (see scheme).
