Bibliography: | 35-1172/06 nanoelectrode ; recessed nanoelectrode ; modified nanoelectrode ; Prussian blue microcrystal Pt nanoelectrodes were fabricated by using a laser-based pipet puller and the recessed nanoelectro- des were prepared by etching of disk Pt nanoelectrodes with high frequency ac voltage. Prussian blue microcrystal was synthesized electrochemically on both disk and recessed Pt nanoelectrodes. The Prussian blue mierocrystal modified nanoelectrode showed a good solid-state cyclic voltammetric behavior. In this paper, a novel method for the controllable synthesis of single particles is proposed which has potential applications in modified electrodes and single particle electrocatalysis.
