As the level of hydrogen sulfide (H2S) is one of the most important indicators of food safety, it is necessary to strengthen the monitoring accuracy of H2S levels in food production. Fluorescence assays are consid-ered as one of the most promising tools for H2S monitoring due to their simplicity, convenience, high accuracy, low cost, and real-time. The rapid progress of fluorescence assays is further promoted by the vigorous development of nanotechnology, and numerous innovative nanotechnology-driven fluorescence assays have been widely used to monitor the H2S levels in food-related matrices. To further accelerate the commercialization of point-of-care fluorescence assays for the portable detection of H2S in food-related matrices, it is necessary to integrate the available knowledge in innovative nanotechnology-driven fluo-rescence assays for H2S detection. The recent investigations concerning six types (metal-based nanoma-terials, metal-organic frameworks, carbon-based nanomaterials, quantum dots-based nanomaterials, silicon-based nanomaterials, and upconversion nanomaterials) of nanomaterials-based fluorescence assays for reporting H2S in food-related matrices were summarized, and its inevitable challenges and prospects were discussed. It helps the development of an efficient early-warning and management method to ensure public food safety.
