【摘要】 近年来过氧化物仿生酶因其在光学、催化、传感以及医学诊断等方面的应用而被广泛的关注。最近研究已发现氢氧化铜纳米笼具有过氧化物仿生酶活性,能催化过氧化氢氧化无色的3,3,5,5—四甲基联苯胺生成蓝色的产物。在本工作中,我们发现莱克多巴胺对氢氧化铜纳米笼仿生酶的催化活性有抑制作用。依据此原理,我们构建了检测莱克多巴胺的比色催化传感器。更多还原

【Abstract】 In recent years, peroxidase mimetics has attained wide attention due to its application in the fields of optics, catalysis, sensor and biomedical diagnosis. A recent investigation has discovered that the copper hydroxide supercage possessed the peroxidase-like activity, and could catalyze the oxidation reaction of 3,3’,5,5’-tetramethylbenzidine by hydrogen peroxide to yield blue product. In this work, we found that ractopamine could inhibit the catalytic activity of the copper hydroxide supercage. On the basis of the principle, we developed a colorimetric catalytic sensor for ractopamine detection.更多还原
