Note (General): Platinum nano-electrodes were fabricated at the success rate 76 % by the six processes; (i) etching a Pt wire in ethanol-water mixture, (ii) sealing it with a glass sheath, (iii) grinding roughly the glass tip, (iv) polishing the tip while monitoring the capacitive ac-current flowing through the glass thin film on the Pt, (v) dissolving the glass film in HF solution until a part of Pt was exposed, and (vi) heating the tip at 85oC for stabilization. A key of the process was to make a thin glass film on the Pt tip (iv) and to expose the Pt surface chemically by (v). 50 electrodes thus fabricated had diameters ranging from 1 nm to 5µm, estimated from the steady-state current of diffusion-controlled current of ferrocene in acetonitrile and ferrocenyl derivative in aqueous solution. They exhibited reproducible and stable voltammograms without hysteresis, withstanding 6 hours' continuous use and 15 hours' iterative processes of heat and voltammetry. Not only the halfwave potentials but also slopes of the log-plots were independent of radii of the electrodes. No kinetic effect was revealed in the steady-state voltammograms.
