• Abstract:A simple method to fabricate gold nanotube by means of a direct electrodeposition is constructed, utilizing anodic aluminum oxide (AAO) as a template. The performances of gold nanoelectrode have been characterized with cyclic voltammetric technique and scanning electron microscope (SEM). The SEM image of as-prepared gold nanoelectrode shows that the surface of electrode was covered with honeycomb gold tube with average pore diameter 200 nm. Its cyclic voltammetric shows the peak current is 6.25 times larger than the bare Au electrode, so the new honeycomb gold nanoelectrode was obviously better than conventional gold electrode. Microperoxidase-11 (MP-11) was immobilized on the electrode and characterized with cyclic voltammetric technique. It was demonstrated that the gold nanotube not only could offer a friendly environment to immobilize MP-11, but also enhance the electron transfer ability between protein molecules and the underlying electrodes.
