A Review on Fluorescent Molecular Probes for Hg²⁺ Ion Detection: Mechanisms, Strategies, and Future Directions

ChemistrySelect, Год журнала: 2025, Номер 10(7)

Опубликована: Фев. 1, 2025

Abstract Fluorescent molecular probes have gained significant attention due to their exceptional attributes, such as enhanced specificity, sensitivity, and reversibility. This review explores how organic probe molecules' fluorescence properties change when metal ions like Hg 2+ bind the receptors. The alteration in results from distinct photophysical mechanisms photoinduced electron transfer, proton energy charge excimer formation, aggregation‐induced emission, C═N isomerization etc. Besides, induce chemical reactions resulting changes structural conformation properties. As a result, this effect specifically affects signal of molecules, which is beneficial for advancing sensor technology developed detect contamination. Focusing on environmental pollution biological sample analysis, study highlights applying fluorescent techniques using chromophores heavy ions, particularly ions. Thus, dyes with modifiable functional groups ensure precise detection offering robust platform monitoring public health safety. We examine capacities, sensing mechanisms, limits, strategies, methodologies utilized. article provides insights into efficacy progress domain sensors detecting

Fluorogenic detection of mercury ion in aqueous environment using hydrogel‐based AIE sensing films

Aggregate, Год журнала: 2022, Номер 4(3)

Опубликована: Окт. 29, 2022

Abstract A “turn‐on” fluorescent sensing strategy was developed for ultrasensitive detection of heavy metal mercury ion (Hg 2+ ) directly in water. It utilized an aqueous soluble aggregation‐induced emission (AIE)‐active probe, named 1,1,2,2‐tetrakis(4‐(1H‐tetrazol‐5‐yl)phenyl)ethene (TPE‐4TA), composing a luminescent tetraphenylene core and multiple anionic tetrazolate spawns. The probe retained dark when molecularly dissolved However, ions can ligate with groups to form infinite coordination polymer particles spontaneously, thus inducing fluorogenic AIE response situ analysis. Moreover, by embedding this molecules hydrophilic polyvinyl alcohol substrate, the resulting hydrogel film allowed Hg on laser‐induced fluorescence analysis setup environment. This worked effectively common environments pH from 4 7.5 showed high sensitivity (limit down 0.38 ppb/1.9 nM), good selectivity wide linearity range quantification. work may lead reliable promising platform on‐site environmental water

Microwave-assisted synthesis of amphoteric fluorescence carbon quantum dots and their chromium adsorption from aqueous solution

Scientific Reports, Год журнала: 2023, Номер 13(1)

Опубликована: Июль 12, 2023

Abstract The chromium adsorption behavior from aqueous solution by the amphoteric Janus nitrogen-doped carbon quantum dots (AJ–N–CQDs) was investigated. pseudo-first-order and second-order kinetics models were employed to analyze experimental data; model presented a better correlation data, suggesting chemisorptions process. values obtained in are still suitable for describing Kinetics of Cr(VI) sorption. These elucidate surface processes involving chemisorption physisorption AJ–N–CQDs. R 2 Boyd gave fit data AJ–N–CQDs (i.e., external diffusion), which means higher value α may be due greater area immediate solution. have fluorescence spectra before after adsorption, indicating they promising chemical sensor applications.
