A self-powered and reusable biocomputing security keypad lock system based on biofuel cells

摘要

(Figure Presented) Locked up! A novel self-powered, reusable biofuel cell (BFC) based biocomputing security system mimicking a keypad lock device using enzymebased concatenated AND logic gates has been developed (see figure; FFD =fructan beta-fructosidase, INV = invertase, GOD = glucose oxidase, URE=urease).
