Current situation in food safety visualization and rapid detection technology by molecularly imprinted fluorescent paper-based sensors

The issue of food safety has always been highly valued by the whole society with the abundance of food types. Traditional food safety inspection methods are time-consuming and highly specialized, which limits their on-site application. The paper based sensor constructed by molecular imprinted polymer combined with ratio based fluorescence sensing technology has gradually become a research focus in the field of food safety detection due to its fast, real-time, low-cost, high accuracy, and portability, demonstrating enormous development potential. This article summarized molecular imprinting technology and the preparation methods of imprinted polymers, with a focus on the application progress of molecular imprinting ratio fluorescent paper-based sensors in the field of food safety visualization and rapid detection technology. In particular, the functionalization technology of paper-based cellulose materials and their applications in rapid detection are proposed to improve their non-specific performance and increase detection sensitivity, Finally, the difficulties and problems that urgently need to be solved in the field of food safety rapid inspection technology were proposed, and the development direction of rapid inspection technology in the field of food safety analysis and detection was prospected, in order to provide a basis for the application and expansion of molecular imprinted fluorescent paper-based sensors.
