Electrochemical enzyme biosensor
First Claim
1. Electrochemical enzyme biosensor which comprises noble metal electrodes and with which an electrochemical oxidation of pyridine necleotides takes place, characterized in that the noble metal electrodes have a microtexture rich in surface pores and have catalytic properties which reduce the overpotential required for electrochemical oxidation of the pyridinine necleotides.

Abstract
In the case of the electrochemical enzyme biosensor comprising noble metal electrodes, an electrochemical oxidation of pyridine nucleotides takes place, in particular of NADH. The noble metal electrodes have a microtexture rich in surface pores and having catalytic properties, as a result of which the overpotential required for electrochemical oxidation of the pyridine nucleotides is reduced. Owing to these microtextures, the surface area of an electrode is from 3 to 10 times larger than its geometric surface area.
