Au-Biocompatible metallic nanostructures in metalloprotein electrochemistry and electrocatalysis

Molecular scale metallic nanoparticles coated by molecular monolayers and immobilized on single-crystal Au-electrode surfaces are efficient catalysts in metalloprotein voltammetry. Nanoparticles prepared by a new “green” method also exhibit strong electrocatalysis in both protein electrochemistry and fuel cell related processes. In this communication we highlight some recent observations and discuss their possible physical origins.
