The fabrication of chemically modified electrode is an active researching field of electrochemistry and electroanalytical chemistry.The modification of electrode with functional polymer film is contributed to the addition of unique functions to electrodes

including selectivity

molecular recognition

pH sensitive

photochemical sensitive and so on

due to the extraordinary structures of the functional polymer films. The unique functions broaden the range of applications of those modified electrodes

and attract more and more attentions. This paper reviews the approaches and the utilized materials of constructing functional polymer films on the electrode in terms of the fabrication of molecular imprinting polymer sensors (MIP sensors) and enzyme sensors

emphasizing on the new applications of electrodeposition in the modification of electrodes. Those approaches could be widely applied to the fabrication of other sensors

possessing an important value of research and applications.
