“…The researchers have also extended the usage of the probe for the detection of Pb 2+ in milk and red wine, with a recovery between 93.7%-103.2%. S. Che et al [88] presented a novel ionic fluorescent probe, IL [HDQ] [P66614], consisting of a functional quinoline-based compound. It works in ethanol solution for Hg 2+ detection.…”

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.

“…The mercury ion, Hg II , as a highly hazardous pollutant, presents a substantial risk to both the environment and human health. The US Environmental Protection Agency regulates the maximum permitted level to 10 nM Hg II for potable water, while the World Health Organization sets the limit to 30 nM Hg II (Che et al, 2023). Merely consuming a small amount of Hg II can result in various toxicological effects, including renal failure, visual impairments, brain damage, migraines, and a decrease in intelligence quotient (Li, Yue et al, 2023;Shi, Li et al, 2023).…”

A new ZnII coordination polymer (CP) based on 2,3-pyrazine dicarboxylic acid (H2pzdc) and 4,4′-bipyridine (bpy) (ZCP) was synthesized using a facile slow evaporation method. Single-crystal X-ray diffraction revealed that ZCP is a two-dimensional porous CP, [Zn2(pzdc)2(bpy)(H2O)2] n , with van der Waals forces as the dominant interaction within its layers forming a 63 network. Employing energetic ultrasound irradiation, nanoscale ZCP (nZCP) was successfully synthesized and Eu3+ ions were incorporated within its host lattice (Eu@nZCP). The resulting platform exhibits superior fluorescence characteristics and demonstrates notable optical durability. Therefore, it was used as a dual detection fluorescent sensing platform for the detection of mercury and L-cysteine (L-Cys) in aqueous media through a turn-off/on strategy. In the turn-off process, the fluorescence emission of Eu@nZCP progressively quenches by the addition of HgII via a photo-induced electron transfer (PET) mechanism. The fluorescence of Eu@nZCP is quenched to establish a low fluorescence background through the incorporation of HgII. This devised turn-on fluorescent system is suitable for the recognition of L-Cys (based on the strong affinity of L-Cys to the HgII ion) through a quencher detachment mechanism. This method attained a relatively wide linear range, spanning from 0.001 to 25 µM, with the low detection limit of 5 nM for the sensing of HgII. Also, the corresponding limit of detection (LOD) for L-Cys is 8 nM in a relatively wide linear range, spanning from 0.001 to 40 µM.

“…41 These derivatives have been observed to effectively detect hydrazine 42 effectively and have recently been used to detect various anions and cations. [43][44][45][46][47] Selecting an optimal uorescence probe requires consideration of quantum yield, absorption/emission wavelengths, photo stability, chemical stability, and Stokes shi. New probes are continually being developed.…”
