Abstract

Cobalt oxyhydroxide nanoflakes (CoOOH NFs), a typical two-dimensional (2D) nanomaterials, were found to induce chemiluminescence (CL) of luminol since the oxidase-like activity of CoOOH NFs enables the dissolved oxygen to generate various radicals (OH, Oand O) even if without the addition of oxidants such as hydrogen peroxide, and these radicals could be scavenged by glutathione (GSH), making GSH could be detected sensitively in the range of 10 nM to 1 μM with the detection limit of 6.4 nM.

摘要

钴氧氢氧化物纳米片(CoOOH NF),一种典型的二维(2D)纳米材料,被发现能够诱导鲁米诺的化学发光(CL),因为 CoOOH NF 的类氧化酶活性使得溶解氧即使在没有添加过氧化物等氧化剂的情况下也能产生各种自由基(OH、O 和 O),而这些自由基可以被谷胱甘肽(GSH)清除,从而使 GSH 能够在 10 nM 至 1 μM 的范围内被灵敏地检测到,检测限为 6.4 nM。
