title: Nanoelectrode array formation by electrolytic nanoparticle impacts.
abstract: We report the fabrication of functional nanoelectrode arrays by the electrolysis of AgBr nanoparticles (NPs) impacting on a glassy carbon electrode from suspension in aqueous solution. The impacted NPs result in Ag NP deposits of similar size to the originating NP, with the coverage of these arrays easily controlled by the time of the deposition step. The NPs constituting the array are deposited randomly across the surface with little aggregation or agglomeration. The fabricated arrays are themselves electrochemically active, mediating the reduction of hydrogen peroxide, H2O2.
