Development of the research on gold nanoparticle-modified electrodes

Abstract

The modification of gold nanoparticles on the surfaces of conducting materials usually develops interesting electrochemical properties that are different from those of conducting materials. Especially, unique electrochemical and catalytic properties of nanostructured gold, which are not available in the bulk state, permit the construction of novel modified electrodes, while realizing some significant contributions to electroanalytical chemistry. Our group has been studying the fabrications and applications of gold nanoparticles-modified indium tin oxide electrodes since 2001. In this account, I introduce some developments of our research on gold-nanoparticle-modified electrodes after 2010, including some achievements in collaborative research as well as research results obtained using platinum nanoparticles. As relatively new topics, the combination of gold nanoparticles with a palladium base electrode and the utilization of non-conducting supporting materials for modifying the vicinity of the electrode surface with gold nanoparticles are described.
