摘要：

Electrochemical organization of a thin film of gold nanoparticles from an aminosilicate-stabilized gold sol on an indium tin oxide coated glass is demonstrated. Films are semitransparent to reflectivity depending on the thickness and have three-dimensional conductivity. Characterization of the films using UV-visible spectroscopy, IR spectroscopy, atomic force microscopy, and cyclic voltammetry has shown that they are made of a network of gold nanoparticles that are interconnected by aminosilicate moieties. This methodology is successfully extended to codeposited glucose oxidase enzyme, based on which a glucose biosensor is demonstrated.
