Graphene Carrier for Magneto‐Controllable Bioelectrocatalysis

Abstract
A magnetically driven fuel‐free graphene carrier loaded with redox‐active cargo‐ferrocene as an electron mediator is fabricated for magneto‐controllable bioelectrocatalysis. The activation and deactivation of redox‐active cargo's redox activity by magnetically driven positioning of the graphene carrier with loaded ferrocene near and away from the conductive support can be employed for magneto‐switchable bioelectrocatalyzed oxidation of glucose by glucose oxidase between active and inactive electrocatalytic states, respectively.
