Food safety has attracted attention worldwide, and how to detect various kinds of hazardous substances in an efficient way has always been a focus. Metal-Organic Frameworks (MOFs) are a class of hybrid porous materials formed by organic ligand and metal ions. Nanoscale MOFs (NMOFs) exhibit great potential in serving as fluorescence sensors for food safety due to their superior properties including high accuracy, great stability, fast response, etc. In this review, we focus on the recent development of NMOFs sensing for food safety. Several typical methods of NMOFs synthesis are presented. NMOFs-based fluorescence sensors for contaminants and adulterants, such as antibiotics, food additives, ions and mycotoxin etc. are summarized, and the sensing mechanisms are also presented. We explore these challenges in detail and provide suggestions about how they may be surmounted. This review could help the exploration of NMOFs sensors in food related work.
食品安全已引起全球关注，如何高效检测各类有害物质一直是焦点。金属有机框架材料（MOFs）是一类由有机配体和金属离子形成的杂化多孔材料。纳米级金属有机框架材料（NMOFs）因其具有高精度、高稳定性、快速响应等优异性能，在食品安全荧光传感方面展现出巨大潜力。在本综述中，我们聚焦于NMOFs用于食品安全传感的最新进展。介绍了几种典型的NMOFs合成方法。总结了基于NMOFs的用于检测污染物和掺假物（如抗生素、食品添加剂、离子和霉菌毒素等）的荧光传感器，并阐述了其传感机制。我们详细探讨了这些挑战，并就如何克服这些挑战提出了建议。本综述有助于在食品相关工作中探索NMOFs传感器。
