Electrochemical detection of commercial silver nanoparticles : identification, sizing and detection in environmental media

The electrochemistry of silver nanoparticles contained in a consumer product has been studied. The redox properties of silver particles in a commercially available disinfectant cleaning spray were investigated via cyclic voltammetry before particle-impact voltammetry was used to detect single particles in both a typical aqueous electrolyte and authentic seawater media. We show particle-impact voltammetry is a promising method for the detection of nanoparticles that have leached into the environment from consumer products which is an important development for the determination of risks associated with the incorporation of nanotechnology into everyday products.
