Bioelectrochemistry is an interdisciplinary subject that deals with the aspects of electrochemistry and electroanalysis characterizing biological processes at the molecular level and relevant to the mechanisms of biological regulation of cells [1]. Nanotechnology has been first used to refer to the ability to engineer materials precisely at the scale on nanometers [2]. Nanotechnology is thus defined as the design and fabrication of materials, devices, and systems with control at nanometer dimensions. So its essence is therefore size and control at the nanometer scale.
