“…The application of this method in analyzing environmental and seafood samples yielded satisfactory results (range of 96.2-105.0%), offering a promising approach for Hg 2+ detection and potential applications in sensing other heavy and transition metal ions. HCDC was amended with dimethylthiocarbamate moieties, serving as a sensor for detecting Hg 2+ in HEPES buffer (5 M, pH = 7.4) medium [90]. This sensor triggers a switch from the thioester group to the ester group of the probe and turns on blue fluorescence.…”

One of the main challenges faced in food safety is the accumulation of toxic heavy metals from environmental sources, which can sequentially endanger human health when they are consumed. It is invaluable to establish a practical assay for the determination of heavy metals for food safety. Among the current detection methods, technology based on fluorescent probes, with the advantages of sensitivity, convenience, accuracy, cost, and reliability, has recently shown pluralistic applications in the food industry, which is significant to ensure food safety. Hence, this review systematically presents the recent progress on novel fluorescent probes in determining heavy metals for food safety over the past five years, according to fluorophores and newly emerging sensing cores, which could contribute to broadening the prospects of fluorescent materials and establishing more practical assays for heavy metal determinations.

A sensitive analytical method for detecting trace levels of mercury(II) in diverse samples is desperately needed owing to its notoriously toxic. In this study, we have developed a novel fluorescent probe 2,2'-((6-hydroxynaphthalen-2-yl) methylene) bis (sulfanediyl) diacetic acid (Probe 1) for the sensitive detection of Hg 2 + . Probe 1 could detect Hg 2 + content in CH 3 CN/buffer (pH 6.0) solution. Probe 1 has a low detection limit (1.34 nM) and the detection range was 0-8 μM. The luminescent intensity of Probe 1 in a CH 3 CN/buffer (pH 6.0) solution increased with the concentration of Hg 2 + over two minutes, as observed under a 254 nm UV lamp. Furthermore, this phenomenon was observed using test papers of Probe 1. Importantly, Probe 1 could detect Hg 2 + in wheat, mineral water, rice, tap water, and kelp samples.

A dual‐function fluorescent probe (Probe 1) was developed for discriminative detection of Hg2+ and N2H4. Probe 1 could discriminatively detect Hg2+ and N2H4 through two different reaction sites, with the mechanism for Probe 1 for Hg2+ depending on a desulfurization reaction and for N2H4 depending on the Schiff‐base reaction. N2H4 had minimal effect on Hg2+ detection in dimethyl sulfoxide (DMSO)/H2O solution, but Hg2+ could interfere with N2H4 detection in DMSO/buffer solution. Different concentrations of Hg2+ and N2H4 resulted in different blue shades of Probe 1 test strips, and the shade of blue was different with the same concentration of Hg2+ or N2H4, as observed under ultraviolet light at 365 nm wavelength.
