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.
我们证明 Co(3)O(4) 纳米粒子(NPs)具有内在的过氧化物酶样活性和过氧化氢酶样活性。Co(3)O(4) NPs 的过氧化物酶样活性源于它们在还原底物和 H(2)O(2)之间进行电子转移的能力,而不是来自生成的˙OH 自由基。作为过氧化物酶模拟物,Co(3)O(4) NPs 被用于 H(2)O(2)和葡萄糖的比色测定。
