Summary:Electrochemical nanoprobes were fabricated from polymer insulated multiwalled carbon nanotube modified tapping mode atomic force microscope probes. An electrochemically active length of carbon nanotube was exposed by laser ablation of the insulating polymer. Characterization of these probes is done by cyclic voltammetry of ferrocenemethanol in an aqueous solution and by finite element analysis. The fabricated nanoelectrodes were found to be stable and yielded an interfacial electron transfer rate constant ( k 0 ) of 1.073 ± 0.36 cm s −1 for ferrocenemethanol. We measured the electron transfer rate of a simple redox reaction on the surface of a single Carbon nanotube mounted on an AFM tip.
