Biosensors Based on Chemically Modified Electrodes with Dehydrogenases as Biological Components
Abstract
Graphite electrodes were modified by adsorption of phenazine methosulphate (PMSt) or N-methyl phenazinium tetracyanoquinodimethane (NMP*TCNQ-) as mediators for NADH-oxidation. Different dehydrogenases were entrapped in a dialysis membrane together with molecular weight enlarged NAD (NAD-PEG). These electrodes could be used for the detection of substrates of dehydrogenases at potentials around 0 mV versus a Ag/AgCl-electrode.Citation
