The as-synthesized porous CuO architectures exhibit high electrocatalytic activity toward the glucose oxidation. When evaluated as a nonenzymatic glucose biosensor, the porous CuO architectures manifest fast response within 1.3 s, wide linear range from 0.5 μM to 2.8 mM, low detection limit of 0.1 μM (signal-to-noise ratio of 3), high sensitivity up to 934.2 μA mM−1 cm−2 as well as favorable reproducibility.Graphical abstract
