Investigation of the Some Electron Transfer Bioprocesses by Voltammetric Techniques

Abstract

This paper is an overview on the electrochemical techniques employed in the 
investigation of electron transfer reactions of biological important compounds at different types of electrodes (mercury or solide electrodes, bare or modified electrodes). We have selected for exemplification, only cytochrome and superoxide dismutase from a large variety of substances of with biological significance participating to electron transfer processes. These processes involve either nonmediated or mediated bioelectrocatalysis. The voltametric technique most often used in this purpose was CV but also some polarographic techniques (DCP, oscillopolarography) were employed. The development of different types of sensors was a direct applicability of such studies.
