Beschreibungen/Notizen

• We report the direct solution‐phase characterization of individual gold‐core silver‐shell nanoparticles through an electrochemical means, with selectivity achieved between the core and shell components based on their different redox activities. The electrochemically determined core–shell sizes are in excellent agreement with electron microscopy‐based results, successfully demonstrating the electrochemical characterization of individual core–shell nanoparticles. Getting to the core of the matter: The electrochemical characterization of core–shell nanoparticles is demonstrated, providing a quantitative approach to measure the core and shell dimensions on an individual nanoparticle basis. Excellent agreement was obtained between this method and electron microscopy analysis, thereby establishing this as a powerful characterization tool for core–shell nanoparticles.
