Electrochemical Methods are widely used in various branches of industry be it, the practical importance of electrochemical processes, role of the processes in living organisms, and the unique features of their experimental study have led to the formation of electrochemistry as an individualistic scientific discipline. The biological processes related to the functioning of biological membranes such as the detection of the visual image, the transmission of the nervous impulse and the assimilation and use of food energy are impossible without electrochemical links.
