Nanomaterial Characterization

Various nanoparticles (≤100 nm diameter) have found significant uses in clothing, sunscreens, food products, food containers, medical treatment and biological imaging owing to their unique size-dependent properties. In order to control and optimize the properties of nanoparticles, their sizes, surface area and concentrations have to be characterized. It is also important that the surface reactivity, catalytic activity and toxicity of the nanoparticles are understood prior to use, especially in medical applications. In our group, we develop electrochemical methods for nanoparticles detection, characterization and investigation of their chemical reactivity via anodic stripping voltammetry and nano-impacts.
