摘要：

A method is presented for the construction of nanometer scale band electrodes based on thin film laminate materials. The electrodes are made using established thin film deposition techniques including metal evaporation and polymer spin coating. Such methods permit fabrication of highly uniform submicrometer metal and insulator layers. The physical nature of the film composite, which is highly flexible and robust, makes it suitable for the assembly of band electrodes in novel designs with a view to electroanalytical applications. The laminate band electrodes fabricated by this film process have been characterized by chronoamperometry and cyclic voltammetry for the reduction of Fe(CN)6(3-) in aqueous KCl solution. A discussion is presented detailing the experimental i-t behaviour with respect to electrode preparation. Extension of thin laminate band electrodes to electroanalysis is also included.
