The Electrochemical Detection and Characterization of Silver Nanoparticles in Aqueous Solution

Abstract

Current spikes after collision: Analysis of current transients arising from impacts between the nanoparticles and an electrode surface (see picture) can be used to detect, identify, and determine the size of silver nanoparticles. This provides an exciting new strategy for the characterization of metal nanoparticles for analytical and environmental monitoring applications.
