Integrating Bimetallic Nanoparticles with Covalent Organic Frameworks as Multifunctional Nanozyme for Colorimetric Detection of Hydrogen Peroxide and Glutathione

引用

Journal of Analysis and Testing 2024年第3期8卷 278-287页

作者： Yuying Yuan Xiaoxue Xi Ting Bao Pingguan Bian feng pei Xiuhua zhang Shengfu Wang Wei Wen Collaborative Innovation Center for Advanced Organic Chemical Materials Co-constructed by the Province and Ministry of Education Key Laboratory for the Synthesis and Application of Organic Functional MoleculesCollege of Chemistry and Chemical EngineeringHubei University Hubei Yihua Chemical Co. Ltd

The controllable growth of metal nanoparticles on nanomaterials is becoming an effective strategy for developing nanocomposites with designated performance. Herein, a simple and mild strategy for the in situ growth of Pt–Pd bimetallic nanoparticles on covalent organic frameworks（COFs） to regulate the nanozyme activity was designed for colorimetric detection of hydrogen peroxide（H2O2） and glutathione（GSH）. The COFs not only offer sufficient loading sites for the uniform dispersion of Pt–Pd bimetallic nanoparticles, but also increase the adsorption of substrate to promote the catalytic reaction. With the bimetallic synergistic effect of Pt–Pd nanoparticles, the prepared multifunctional nanozyme（Pt–Pd/COFs nanozyme） simultaneously exhibited superior peroxidase（POD）-like activity and oxidase（OXD）-like activity. Using the multifunctional nanozyme, a colorimetric sensing system was constructed for sensitive detection of H2O2and GSH, with the wide linear ranges of 5–1000 μmol/L and 1–40 μmol/L, and the detection limits were 1.14 μmol/L and 0.43 μmol/L, respectively. It was successfully used for the detection of real samples in environmental water and serum, providing a simple method for disease diagnosis and environmental monitoring.
