Single collisional events of platinum nanoparticless on carbon. (a) A 60 s FSCV recording at ν = 400 V/s showing detection of 5 Pt nanoparticles on a 5 μm CFE in a 15 mM hydrazine solution. (b) Current–time trace taken from (a) at +0.1 V showing single-particle current peaks similar to that recorded with amperometry. (c) Background-subtracted CV of a 4 nm Pt particle recorded at 7.7 s in (a). Reproduced with permission from ref 45. Copyright 2014 American Chemical Society.
