Abstract

original image

The size of organic nanoparticles (NPs) can be electrochemically determined by Faradaic charge transfer when nanoparticles strike an electrode. Indigo NPs were used as a model (see distribution of the NP diameter). This strategy could be used for monitoring the size of a wide range of organic nanoparticles.
