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.
