Electrochemical processes are central to corrosion, energy storage, catalysis, and biology. Beyond topography scanning electrochemical microscopy (SECM) measures reaction rates and electrochemically generated species. Here, we demonstrate the capability of Scuba Probe Technologies insulated cantilevers to measure electroactive species being generated at the sample surface. By probing a micro electrode array in hexaammineruthenium (III) chloride operating in sample generation-tip collection mode, we demonstrate that electrical currents on the order of a few pA are observed. Correlating current (top) with topography (bottom) allows for identification of both active and inactive electrodes.
