金属有机框架（MOFs）在食品安全传感器中的应用

The application of Metal-Organic Frameworks (MOFs) in food safety sensors

摘要

金属有机框架因其均匀的结构、巨大的表面积、极高的孔隙率以及表面易于修饰等特性，近年来在食品污染物检测领域的传感器应用上越来越受到重视。这篇综述文章详细介绍了利用基于金属有机框架的传感器技术，如发光、电化学、电化学发光和比色传感器等，来检测食品中的污染物，包括农药残留、真菌毒素、抗生素、食品添加剂以及其他潜在的危险物质并对它们的性能进行了比较和讨论。此外，文章还深入探讨了每种传感器的主要局限性，并讨论了金属有机框架如何通过其增强机制来解决这些问题。

Abstract

Metal-organic frameworks have attracted more and more attention in the field of food contaminant detection due to their uniform structure, huge surface area, extremely high porosity and easy surface modification. This review article details the use of metal-organic framework based sensor technologies such as luminescence, electrochemistry, electroluminescence, and colorimetric sensors to detect contaminants in food, including pesticide residues, mycotoxins, antibiotics, food additives, and other potentially hazardous substances, and compares and discusses their performance. In addition, the paper delves into the main limitations of each sensor and discusses how metal-organic frameworks can address these issues through their enhancement mechanisms.
