title: Self-powered biomolecular keypad lock security system based on a biofuel cell.
abstract: The enzyme-based keypad lock was integrated with a biofuel cell yielding a self-powered biomolecular information security system. The correct "password" introduced into the keypad lock resulted in the activation of the biofuel cell, while all other "wrong" permutations of the enzyme inputs preserved the "OFF" state of the biofuel cell.
