Abstract
Abstract There is disclosed a chemically modified electrode which consists of an electrically conducting pyrolytic graphite electrode the basal plane of which is exposed, and a redox/adsorption electron mediator immobilized on the surface of the electrode. The electron mediator is, for example, viologen dye, bipyridine, phenanthroline, 1-methoxy-5-methylphenazenium methyl sulphate or N-methylphenazenium methyl sulphate. The electrode is used in the detection of biological substances.
