Estimating the term…
Electrodes for the electrochemical regeneration of the co-enzymes, NADH, NADPH or analogs thereof. The electrode surface has been modified by adsorbing thereto a condensed aromatic ring system comprising at least three, preferably four or more, condensed aromatic rings. A method of preparing the electrodes is also described, in which a condensed aromatic ring system is adsorbed to the surface of carbon or a graphitic material. Finally, there is described the use of said electrodes for the electrochemical regeneration of co-enzyme in biochemical, microbiological or biochemical processes as the anode in biochemical fuel cells or for analysis in systems utilizing co-enzyme-dependent enzyme.
An electrode for the electrochemical regeneration of coenzymes dihydronicotinamide adenine dinucleotide (NADH), dihydronicotinamide adenine dinucleotide phosphate (NADPH), or analogs thereof, characterized in that it comprises carbon or a graphitic material to the surface of which is adsorbed a condensed aromatic ring system comprising phenoxazinium ions, phenoxazinones, phenothiazinium ions or phenothiazinones, substituted or unsubstituted.
A method of making an electrode for the electrochemical regeneration of the coenzymes dihydroicotinamide adenine dinucleotide (NADH), dihydronicotinamide adenine dinucleotide phosphate (NADPH), or analogs thereof, characterized in that there is adsorbed to the surface of the electrode which consists of carbon or a graphitic material a condensed aromatic ring system comprising phenoxazinium ions, phenoxasinones, phenothiazinium ions or phenothiazinones, substituted or unsubstituted.
In a method of electrochemical regeneration of coenzymes for biotechnical, microbiological, or biochemical purposes, the steps of providing an electrode comprising carbon or a graphitic material to the surface of which is adsorbed a condensed aromatic ring system comprising phenoxazinium ions, phenoxazinones, phenothiazinium ions or phenothiazinones, substituted or unsubstituted, and employing said electrode in an electrochemical cell for the regeneration of coenzymes dihydronicotinamide adenine dinucleotide (NADH), dihydroniciotinamide adenine dinucleotide phosphate (NADPH), or analogs thereof.
A method of improving the performance of a biochemical fuel cell which operates with dehydrogenases as catalysts and with coenzyme as energy-transferring redox pair, which comprises providing an electrode comprising carbon or a graphitic material to the surface of which is adsorbed a condensed aromatic ring system comprising phenoxazinium ions, phenoxazinones, phenothiazinium ions or phenothiazinones, substituted or unsubstituted, and operating said fuel cell with said electrode serving as the anode thereof.
A method of analysis in systems utilizing coenzyme-dependent enzyme, the comprises providing an electrode comprising carbon or a graphitic material to the surface of which is adsorbed a condensed aromatic ring system comprising phenoxazinum ions, phenoxazinones, phenothiazinium ions or phenothiazinones, substituted or unsubstituted, and employing said electrode in an analytical apparatus in which coenzymes dihydronicotinamide adenine dinucleotide (NADH), dihydronicotinamide adenine dinucleotide phosphate (NADPH), or analogs thereof are generated.
