Abstract:We demonstrate a method for fabrication of a Scanning ElectrochemicalMicroscopy (SECM) probe using a parylene coated Carbon Nanotube as a nanoscaleelectrode. Parylene is used to achieve a conformal pinhole free insulatinglayer, which is a major prerequisite for simultaneous topographical andelectrochemical imaging applications. A controlled length of carbon nanotube
is exposed, to act as electrochemically active area which has very fast interfacial electron transfer rate, by local removal of the insulating polymer. Calibration of these probes is done by cyclic voltammetry in aqueous solution. Other novel probe designs are also suggested.
