Abstract

The H₂O₂-mediated enlargement of Au nanoparticles (NPs) and the growth mechanism are described. In addition to the deposition of gold on the NP faces, the formation of nanocrystalline clusters at the intersection of the faces is observed. The detachment of the latter nanoclusters provides additional seeds for the deposition of gold. The biocatalyzed generation of H₂O₂ in the presence of O ₂/glucose and glucose oxidase enabled the development of an optical biosensor for glucose.
