Magnetic ZIF-8-Based Mimic Multi-enzyme System as a Colorimetric Biosensor for Detection of Aryloxyphenoxypropionate Herbicides.

本研究通过在一锅法中将芳氧苯氧丙酸（AOPP）除草剂水解酶QpeH和醇氧化酶AOx封装于含磁性Fe3O4纳米颗粒（MNPs）的沸石咪唑酯骨架材料（ZIF-8）纳米晶中，构建了磁性模拟多酶系统QpeH/AOx@mZIF-8，用于AOPP除草剂检测。采用扫描电镜、X射线衍射、傅里叶变换红外光谱、热重分析、氮吸附和振动样品磁强计表征其形貌...
