Popis:	The fabrication of a three-electrode electrochemical microcell in which the working electrode is selectively modified with poly (vinylferrocene) (PVFer) is described for use as a chemical sensor. The microcell was characterized by cyclic voltammetric and differential-pulse voltammetric techniques and the behaviour of the PVFer-modified platinum electrode in contact with 0.1 M KCl is reported. The mediating properties of the PVFer film are demonstrated for this cell by using the oxidation of ascorbic acid, a process which is shown to be slow at the corresponding bare platinum microelectrode.
