Abstract

AbstractThis article is an overview of extensive research efforts in many laboratories in the last two decades in the area of magneto‐switchable electrochemical systems. Electrochemical reactions, including electrocatalytic and bioelectrocatalytic processes, have been reversibly activated and inhibited upon physical translocation and reorientation of different magnetic micro/nano‐species on electrode surfaces, particularly using magnetic micro/nanoparticles, adaptive nanowires and hybrid‐graphene sheets. These processes were triggered by repositioning an external magnet, thus resulting in changes in magnetic field at the electrode interfaces. Coupling of the magneto‐activated electrochemical systems with enzymatic reactions of various complexity allowed sophisticated bioelectronic devices for tunable biosensing, on‐demand power production, unconventional computing and other novel bioelectronic applications.
