In this paper, we successfully fabricated a novel type of a hollow CuO polyhedron that consists of numerous nanoplates using Cu2O as a template. The hollow CuO polyhedron-modified electrode exhibits high sensitivity, low detection limit, good stability and fast response towards the oxidation of glucose, suggesting it to be a promising nonenzymatic glucose sensor.

Cu 2 O cubes and octahedra which have different crystallographic facets have been used for the nonenzymatic glucose sensors. The electrode based on the Cu 2 O octahedra displays much higher sensitivity, wider linear range and lower detection limit than that of the cubes modified electrode, which could be attributed to the different atomic arrangements of the exposed surface.
