Abstract: This research introduces the use of “bucky” papers based on SWNTs as anode electrode materials for the oxidation of NADH and L-Malate oxidation by poly(methylengreen) and malate dehydrogenase respectively. SWNTs were used to create an electrode design consisting of high surface area-hierarchically ordered carbon nanomaterials with controlled surface chemistry. Additionally, this research introduces new cathodes designs based on buckeye and toray papers for air-breathing and liquid electrolyte modes. Buckeye and 0.11mm-thick toray papers are used to design the air-breathing cathode by immobilization of Laccase using a non-covalent linking agent. The liquid electrolyte cathode, designed to be applied in implantable devices, consists of 0.28 mm-thick toray paper as conductive material and Bilirrubin oxidase, the biocatalyst, immobilized silica-gel. The composite nanomaterials and the immobilization techniques utilized in this research would help as departing stage to engineer electrodes designs that meet the criteria required for optimum biofuel cells.
