Collisions of several kinds metal or oxide single nanoparticles (NPs) with a less catalytic electrode surface have been observed through amplification the current by electrocatalysis. Two general types response, staircase blip (or spike) are seen particle collisions. The responses were caused random individual events as function time rather than usual continuous an ensemble large number events. treatment stochastic electrochemistry like NP collisions is different from model for ensemble-based electrochemical behaviour. Models discussed, including simulations, and frequency steps blips investigated systems experimentally.
