Recent advances in sensing platforms based on metal/covalent organic framework for the detection of food-borne organic contaminants

Foodborne organic contaminants against health, mainly including antibiotics, pesticides, mycotoxins, foodborne bacteria, etc., have been considered one of the global public health problems. The early detection of these organic contaminants before consumption can significantly reduce the risk of acute or chronic food poisoning. Therefore, it's of great significance to develop effective sensing strategies for convenient, rapid, sensitive, and selective food quality monitoring. Metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), as highly promising porous materials with multifunctionality, exhibit broad prospects in the field of chemical or biological sensing. They possess great potential to meet the requirements for detecting numerous analytes. Here, we summarized the recent advances of functional MOFs- and COFs-based efficient sensing platforms developed for the measurement of foodborne contaminants. In addition, a brief discussion of the future challenges in the practical application of these platforms and insights into the future directions in this promising field was also included.
