“…However, due to the low atomic utilization, the catalytic efficiency of nanozymes is lower than that of natural enzymes. SAzymes with a single metal atom as the active center and 100% atom utilization show catalytic activity close to or even higher than that of natural enzymes and high stability, which is ideal for practical applications. , The SAzyme-based assays for food safety inspection and nutrient assessment show advantages such as simplicity, rapidness, high sensitivity, and stability and the possibility of on-site testing. Meanwhile, the combination of SAzymes with electrochemiluminescence, colorimetric sensors, and sensor arrays can effectively improve their detection sensitivity.…”

Single-atom nanozymes (SAzymes) have been greatly developed for rapid detection, owing to their rich active sites and excellent catalytic activity. Although several excellent reviews concentrating on SAzymes have been reported, they mainly focused on advanced synthesis, sensing mechanisms, and biomedical applications. To date, few reviews elaborate on the promising applications of SAzymes in food safety inspection and food nutrition evaluation. In this paper, we systematically reviewed the enzyme-like activity of SAzymes and the catalytic mechanism, in addition to recent research advances of SAzymes in the domain of food safety inspection and food nutrition evaluation in the past few years. Furthermore, current challenges hampering practical applications of SAzymes in food assay are summarized and analyzed, and possible research areas focusing on SAzyme-based sensors in rapid food testing are also proposed.

“…Metal ions enter and accumulate in the human body via the food chain, lead to many diseases threatening human health. Therefore, it is essential to develop effective, rapid detection methods for metal ions [61]. As shown in the Figure 3 reveal that they both show obvious fluorescence enhancement effect to high valence metal ions (Fe 3+ , Al 3+ , Cr 3+ , In 3+ and Zr 4+ ) [66].…”

As more and more pollutants threaten human health, it is necessary and essential to develop sensitive, accurate and rapid methods and sensory materials to detect harmful substance. Metal-organic frameworks (MOFs) are inorganic-organic hybrids assembled from inorganic metal ions or clusters and suitable organic ligands. Zinc-based MOFs (Zn-MOFs) have emerged as one of the most promising sensory material of MOFs for practical applications, and attracted significant attention due to structural diversity and incomparable stability properties. However, there are few reviews on systemic summary of synthesis design, mechanism and application of Zn-MOFs. In this review, we summarize the synthesis design methods, structure types and luminescence mechanism of Zn-MOFs sensor recognition in the past ten years and their applications in metal cations, anions, organic compounds and other analytes. Finally, we present a short conclusion, and look forward to the future development direction of Zn-MOFs.
