Zinc ion detection using a benzothiazole-based highly selective fluorescence “turn-on” chemosensor and its real-time application

Abstract

A new photochromic fluorescence chemosensor was devised and effectively synthesized using benzothiazole and imidazopyridine derivatives.

A Near‐IR Fluorimetric Chemosensing System for the Turn‐On Detection of Hydrogen Sulfate Anion

“…Among these studies, fluorimetric chemosensors have come to the fore with their easy, fast, and precise measurement. [5][6][7][8][9] One of the first studies on fluorescent bisulfate chemosensors was carried out by Tang et al [10] In this study, the cation in a fluorescent chelate displaces with the proton of HSO 4 À ion and converts it into a non-fluorescent structure. Under the same conditions, another anion with acidic properties, H 2 PO 4 À , also causes some decrease in fluorescence.…”

“…Therefore, various studies have been carried out to provide selective detection and quantification of this ion. Among these studies, fluorimetric chemosensors have come to the fore with their easy, fast, and precise measurement [5–9] …”

Zinc-Induced Luminescent l-Valine-Based Pseudopeptidic Soft Bioinspired Materials for Precise Tuning of Nanoassembly

“…Therefore, much effort has been oriented toward the judicious design and synthesis of appropriate fluorescence sensors for the quantitative detection and determination of various metal ions. , Zn­(II) ion is an essential element that influences various biological activities that play significant roles in environmental and biological systems. , Zinc is the second most abundant metal ion in the biological system. It is crucial for maintaining normal cellular activities, including cell division, mammalian reproduction, muscle contraction, hormone regulation, protein synthesis, and DNA synthesis. − In the human body, the normal Zn­(II) level is between 200 and 300 mg, and deviation of zinc levels (above or below) from this value can cause many health problems. A deficiency of Zn­(II) may cause several symptoms of diseases, such as brain dysfunction, Parkinson’s disease, immune suppression, skin damage, diabetes, and slow growth .…”

A pyrene-induced PET-based chemosensor for biologically important Zn(ii) ions: application in test strips and live cell imaging studies

“…Owing to their major importance in medical, biomedical, biological, environmental, industrial, and other fields, the design and development of novel efficient molecular sensors for the selective recognition of heavy and transition metal (HTM) ion/s have attracted significant interest from chemists. 1 Due to their greater biological impact, zinc ions (Zn 2+ ) have become the most targeted element for many researchers in biological and chemical sciences. Among the various elements, Zn 2+ is the second most prevalent heavy d-block metal ion after iron in the human body for sustaining life.…”
