Bioelectrocatalysis: Graphene Carrier for Magneto‐Controllable Bioelectrocatalysis (Small 4/2014)

Fuel-free magneto-controllable bioelectrocatalysis based on a graphene carrier loaded with redox-active cargo as an electron mediator is reported by B. Ma, X. D. Chen, and co-workers on page 647. The activation and deactivation of the redox-active cargo's redox activity by the magnetically driven complex graphene carrier can be employed for magneto-switchable bioelectrocatalyzed oxidation of glucose by glucose oxidase between active and inactive electrocatalytic states. This development has great potential in magneto-switchable biofuel cells, fuelfree magnetobioelectronics, controlled biomedical drug delivery, etc.
