Multiple logic gates based on electrically wired surface-reconstituted enzymes

The electrode functionalized with glucose oxidase (GOx) and microperoxidase-11 (MP-11) performs various Boolean logic operations (OR, XOR, AND-OR) upon addition of glucose and/or H2O2 and application of different potentials. The output signal coming from the electrically wired enzymes is electrochemically readable, allowing interfacing of biochemical computing systems with ordinary electronics.
