A chemically modified electrode (CME) is an electrical conductor (material that has the ability to transfer electricity) that has its surface modified for different electrochemical functions. CMEs are modified using advanced approaches to electrode systems by adding a thin film or layer of certain chemicals to change properties of the conductor according to its targeted function.〔Alkire, R., Kolb, D., & Lipkowski, J., Chemically modified electrodes, Germany: Wiley-VCH, Weinheim, 2009〕 At a modified electrode, an oxidation-reduction substance accomplishes electrocatalysis by transferring electrons from the electrode to a reactant, or a reaction substrate.〔Murray R. W.,Goodenough J. B. and Albery W. J., Modified Electrodes: Chemically Modified Electrodes for Electrocatalysis, The Royal Society, 1981, pp. 253-265, http://www.jstor.org/stable/36940〕 Modifying electrodes' surfaces has been one of the most active areas of research interest in electrochemistry since 1979, providing control over how electrodes interacts with their environments.〔 == Description == Chemically modified electrodes are different from other types of electrodes as they have a molecular monolayer or micrometers-thick layers of film made from a certain chemical (depending on the function of the electrode). The thin film is coated on the surface of the electrode. The outcome would be a modified electrode with special new chemical properties in terms of physical, chemical, electrochemical, optical, electrical, transport, and other useful properties.〔Durst, R., Baumner, A., Murray, R., Buck, R., & Andrieux, C., Chemically modified electrodes: Recommended terminology and definitions, IUPAC, 1997, pp 1317-1323, http://old.iupac.org/publications/pac/1997/pdf/6906x1317.pdf〕 CMEs and electrodes in general heavily depend on electron transport: A general term for electrochemical processes where the charge transports through the chemical films to the electrode. The term coverage is used to express the area-normalized in mol/m^2 of a specific type of chemical site in the thin chemical film in on the surface of the chemically modified electrode.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chemically modified electrode」の詳細全文を読む スポンサード リンク
