We demonstrate that Co(3)O(4) nanoparticles (NPs) exhibit intrinsic peroxidase-like activity and catalase-like activity. The peroxidase-like activity of the Co(3)O(4) NPs originates from their ability of electron transfer between reducing substrates and H(2)O(2), not from ˙OH radical generated. As peroxidase mimetics, Co(3)O(4) NPs were used for colorimetric determination of H(2)O(2) and glucose.
