Title: Atomic Force Microscopy of Electrochemical Nanoelectrodes
Abstract: Nanometer-sized electrodes have recently been used to investigate chemical and biological systems on the nanoscale. Although offer a number of advantages over macroscopic probes, visualization of their surfaces remains Thus, the interpretation of the electrochemical response on assumptions about the electrode shape and size prior to the and the changes induced by surface reactions (e.g., In this paper, we present first AFM images of which provide detailed and unambiguous information about electrode geometry. The effects of polishing and cleaning are investigated, and AFM results are compared to those by voltammetry and SEM. In situ AFM is potentially useful for monitoring surface reactions at nanoelectrodes.
