The invention concerns a bioelectrode and a device comprising same, for detecting or oxidising glucose. The bioelectrode of the invention comprises a layer of carbon nano tubes to which aromatic molecules are bonded, and FAD-GDH enzymes being adsorbed on the aromatic molecules. The invention applies to the field of biosensors and biofuel cells in particular.

Bioelectrode for detection and/or oxidation of glucose, its production method and device

A biofuel cell intended to be immersed into a liquid medium containing a sugar and oxygen, wherein the anode includes an enzyme capable of catalyzing the oxidation of the sugar and a redox mediator of low redox potential capable of exchanging electrons with the anode enzyme and the cathode includes an enzyme capable of catalyzing the reduction of oxygen and a redox mediator of high redox potential capable of exchanging electrons with the cathode enzyme. Each of the anode and cathode electrodes is formed of a solid agglomerate of a conductive material mixed with the appropriate enzyme and redox mediator and is solid with an electrode wire.
