In this paper, a method of carbon nanotube coated with the dendrimer encapsulated platinum nanoparticles(Pt-DENs/CNTs) was introduced, and the properties of enzyme electrode modified by the Pt-DENs/CNTs were investigated. The formation of the self-assembled (GOx/Pt-DENs)n/CNTs construction was expiored by high resolution transmission electron microscopy (HRTEM). And the results indicated that the uniform growth of the layer-by-layer nanostructures onto carboxyl-functionalized CNTs. The electrochemical properties of the enzyme anode modified by (GOx/Pt-DENs)n/CNTs, which act as biofuel cell anode, was studied by electrochemica measurements. Owing to its nanostructure, the (GOx/Pt-DENs)n/CNTs heterostructures have a large specific area, a high surface active center, good conductivity and macro tunnel effect, therefore the electrode modified by (GOx/Pt-DENs)n/CNTs has series of attractive electrochemical characteristics so as to enhance biofuel cell’s function.
