Abstract

This work reports the fabrication of disposable bismuth microelectrode arrays by a thin-film microengineering approach and their application in stripping voltammetry. The microelectrode array was fabricated by sputtering and photolithography and consisted of 625 bismuth microdisks 10 μm in radius with centre-to-centre separation of 200 μm. The detection of trace metals, by stripping voltammetry, was carried out in unstirred solutions containing low concentrations of supporting electrolyte. These sensors provided enhanced analytical characteristics compared to conventional bismuth-film electrodes (BiFEs). © 2011 Published by Elsevier Ltd.
