This article describes the controllable construction of a layered superstructure of gold nanooctahedra via a molecularly mediated assembly and their electrochemical application as a host matrix toward the oxidation of glucose. The layered superstructures of the An nanooctahedra were confirmed with atomic force microscopy, X-ray electron spectroscopy, and cyclic voltammograms. The effects of the interface of gold spherical nanoparticles and the different layered interface of gold nanooctahedra on the electrochemical responses to Fe(CN)(6)(3-) and glucose were investigated in detail. The glucose biosensor, which uses the Air nanooctahedra layer structure as a matrix, shows excellent electrocatalytic activities, such as a high level of sensitivity, a fast response, and a wide response range.
