Abstract :
Food safety is one of the most critical public health issues, directly affecting human health and well-being. In today’s world, with the expansion of the food supply chain and growing concerns over microbial, chemical, and biological contamination, there is an increasing need for rapid, accurate, and reliable methods to monitor food safety and quality. In this regard, smartphone-based sensors have emerged as an innovative and cost-effective solution. These sensors, leveraging the advanced imaging and image-processing capabilities of smartphones, enable the quick and precise detection of contaminants and harmful substances. Fluorescence sensors operating via an “on–off–on” mechanism have attracted significant attention due to their high sensitivity and excellent selectivity. This article provides a comprehensive review of smartphone-based sensing platforms that utilize the “on–off–on” fluorescence mechanism, introducing common fluorescent materials and the principles behind their design. In addition, recent applications of these sensors in food safety detection, along with current challenges and future development directions, are discussed.
