‘Non-destructive’ biocomputing security system based on gas-controlled biofuel cell and potentially used for intelligent medicaln diagnostics

摘要

Motivation: Biofuel cells (BFCs) based on enzymes and microbes are the promising future alternative sources of sustainable electrical energy under mild conditions (i.e. ambient temperature and neutral pH). By combining the adaptive behavior of BFCs self-regulating energy release with the versatility of biocomputing, we construct a novel gas-controlled biocomputing security system, which could be used as the potential implantable self-powered and ‘smart’ medical system with the logic diagnosis aim.
