In this work, we report a zeolitic imidazolate framework (ZIF-67) which could catalyze 3,3′,5,5′-tetramethylbenzidine (TMB) to produce a yellow chromogenic reaction. ZIF-67 showed high peroxidase-like activity compared with copper-based metal−organic framework nanoparticles (Cu-MOF), zinc-based metal−organic framework nanoparticles (ZIF-8), and horseradish peroxidase (HPR). We discovered for the first time that the cobalt-based metal−organic framework nanoparticles possess intrinsic peroxidase-like activity without H2O2, which can be employed to quantitatively monitor the H2O2.

超薄ZIF-67纳米片作为过氧化物酶样催化的比色生物传感平台
在这项工作中,我们报告了一个沸石咪唑盐骨架(ZIF-67),它可以催化3,3',5,5'-四甲基联苯胺(TMB)产生黄色的发色反应。与铜基金属有机框架纳米颗粒(Cu-MOF),锌基金属有机框架纳米颗粒(ZIF-8)和辣根过氧化物酶(HPR)相比,ZIF-67表现出高的过氧化物酶样活性。我们首次发现钴基金属有机骨架纳米粒子具有固有的过氧化物酶样活性,而没有H 2 O 2,可用于定量监测H 2 O 2。
