Chemically modified electrode

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.

At a modified electrode, an oxidation-reduction substance accomplishes electrocatalysis by transferring electrons from the electrode to a reactant, or a reaction substrate.

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.

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.
