Title: Hopping mode SECM imaging of redox activity in ionic liquid with inlaid platinum nanoelectrodes prepared using a heating coil puller
Abstract: Major difficulties in nanoscale scanning electrochemical microscopy resulting from the short tip-to sample distance, are tilt and vertical thermal drift. This renders constant height nanoscale electrochemical imaging experimentally problematic. SECM also requires application of reliable nanoprobes. SECM nanotips are commercially available, they are rather fragile and their shelf-life is limited. Many SECM employ self-prepared nanoprobes, fabricated using advanced In this paper, we employ a hopping mode approach to nanoscale imaging, which resolves the mentioned common The applied platinum nanoelectrodes, insulated with glass, were prepared using affordable equipment and They were applied for nanoscale mapping of redox mediator at a model interdigitated microsensor, composed of Pt electrodes, in a solution of ferrocene in viscous hydrophobic temperature ionic liquid (RTIL) - (C(4)mim The presented nanosensors were also characterized with cyclic in aqueous electrolyte containing hexamineruthenium (III) chloride as redox mediator.
