The electrodes utilise nanometric holes milled in a silicon nitride based pasivation layer, followed by wet etching of a silicon oxide based pasivation layer, to expose an underlying gold electrode. After functionalisation using a surface assembled monolayer and an electrochemically grown polypyrrole, these gold nanoelectrodes have been tested, via cyclic voltammetry, in the detection of [Fe(CN)(6)](4-/3-) ions. The nanoelectrodes will be used to investigate the electrical properties of nanometric biological specimen. (c) 2007 Elsevier B.V.
