A facile and total water-soluble fluorescent organic nanoparticles-based sensor for Hg2+ detection and its application in tea samples

Fluorescent Schiff base sensors as a versatile tool for metal ion detection: strategies, mechanistic insights, and applications

“…3.5.3 Real sample analysis 185,280,[282][283][284][285] . Although the fluorescent sensors for metal ion detection have shown advantages such as simplicity, selectivity, sensitivity, and rapid response time over other analytical methods, working with some toxic metal ions has always been problematic due to strong hydration, poor coordination, and lack of spectroscopic characteristics.…”

A facile synthesis of a novel 4-hydroxyl-3-azo coumarin based colorimetric probes for detecting Hg2+ and a fluorescence turn-off response of 3CBD to Fe3+ in aqueous environment

“…To date, a few aqueous based sensing probes have been reported in literature, however, most are haunted by crossdetection problem. [34][35][36][37] Thus, the detection of heavy metal cations in aqueous environments are still high on the priority list, due to their prospective of developing eld-based sensing kits, 14,[38][39][40][41] which can be readily used anywhere, including rural areas. In addition, aqueous solution-based sensing probes can be essential in physiological systems, for monitoring the presence and concentration of specic cations of concern, and be able to regulate them.…”

Synthesis, “turn-on” fluorescence signals towards Zn2+ and Hg2+ and monoamine oxidase A inhibitory activity using a molecular docking approach of morpholine analogue Schiff base linked organosilanes

“…To date, fluorescence-based probes have been chosen as the best detector for Zn 2+ and Hg 2+ due to their low cost, quick response and high sensitivity. 19–23…”

“…To date, fluorescence-based probes have been chosen as the best detector for Zn 2+ and Hg 2+ due to their low cost, quick response and high sensitivity. [19][20][21][22][23] Heterocycles are nitrogen, oxygen and sulphur containing compounds widely used in medicinal chemistry due to their biological activity. 24,25 Morpholine is one of the heterocyclic moieties containing both amine and ether functionality that is extensively used as a pharmacophore in clinical areas.…”
