Immobilization Of Enzymes Onto Thienoviologen-modified Gold Electrodes

Abstract

Utilization of new molecular electronics compounds and their self-assembly on electrode surfaces is a new promising strategy for the production of enzyme electrodes. Our present study involves self-assembly of thienoviologens, a novel type of donor-acceptor heterocyclic oligomers, on gold electrodes and the assessment of conductivity of the formed layers. We also present the results of a preliminary study of the adsorption of two enzymes, glucose oxidase (GOx) and choline oxidase (ChOx), onto the thienoviologen layers.
