✦ Synopsis

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 etectroanalytical applications . The laminate band electrodes fabricated by this film process have been characterized by chronoamperomctry and cyclic voltammetry for the reduction of Fe(CN)6 -in aqueous KCI 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 .
