The recently emerged magnetoswitchable electrochemical and bioelectrochemical systems have inspired the design and construction of very sophisticated adaptive bioelectronic devices controlled by external magnetic signals [54]. These devices will find numerous applications in different areas of bioelectronics and particularly in switchable/tunable BFCs.
