Biotemplated synthesis of Au nanoparticles-TiO2 nanotube junctions for enhanced direct electrochemistry of heme proteins

Chem Commun (Camb). 2013 Jan 28;49(8):774-6. doi: 10.1039/c2cc38183d.

Abstract

Au nanoparticles (AuNPs) are assembled on TiO(2) nanotube (TiNT) arrays by combining a biotemplating method with the unique photocatalytic properties of TiO(2). The formed AuNPs-TiNT junctions show highly improved electrochemical conductivity and act as electrode materials to achieve the enhanced direct electrochemistry of heme proteins.
