Voltammetric Response on a Puller-Made Nanometer-Sized Electrode

The method of fabrication of electrodes by using a laser-puller is a commonly used method to produce small electrodes. Simulation shows that the taper-shaped insulation layer of a puller-made electrode has an obvious effect on its voltammetric response, especially when the electrode has a small RG (the ratio of the insulating sheath radius to the electrode radius). The effect of low-pass filtering on the voltammetric response of a very small puller-made electrode has also been studied.
