We introduce \u201cOpto-iontronic Microscopy\u201d that monitors redox activity from changes in scattered light inside a single nanohole. Electric-double-layer modulation with lock-in detection delivers label-free sensitivity to this attoliter volume, while a reaction\u2013transport model links the optical signal to local reactant and product concentrations. By resolving ferrocenedimethanol oxidation\u2013reduction in real time, we disentangle double-layer charging from Faradaic currents and quantify nanoscale electrochemistry. This approach enables high-throughput maps of activity in confined geometries, informing catalyst design, battery interface engineering, and single-entity electrochemistry.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Agenda: 1:30 p.m.\u00a0 Join us for afternoon tea with delightful snacks 2:00 p.m.\u00a0 Brief introduction by Marek Piliarik 2:05 p.m.\u00a0 Lecture by prof.
