✦ Synopsis

The present paper is the first report on an enzymatic logic gates system based on oxygen-controlled biofuel cell (BFC). By accepting dual gas-input signals and resulting in the maximum power output changes of the compartmentless BFC with bioanode/biocathode-immobilized enzymes, such system permits AND and XNOR Boolean logic gates readily achieved, reset and interconverted into each other in "one pot". On the basis of the built-in Boolean XNOR logic, the proof-of-concept oxygen-controlled biocomputing system with miniature BFC operating in serum enabled us to construct a potential self-powered and implantable medical system with the diagnosis aim, which could intellectually make logic decisions that whether the dissolved oxygen content in body fluid is within normal limits or not.
