Abstract It is still challenging to directly recognize the anionic species [UO 2 (CO 3 ) ] 4− , dominant in environment (82%‐93%), using current optical probes because of adverse effects its thick hydration shell on binding interactions. In this study, a water‐soluble Pt(II) methylated terpyridine complex ([Pt(CH ‐tpy)NCO] + supramolecular probe designed target by new strategy overlapping arrangement. The response demonstrates excellent selectivity among ≈30 investigated interfering substances, along with rapid (≈15 s), high sensitivity (64.1 n m and dual‐signals. confirmed both experimentally theoretically that superior detection performance attributed formation unique structure featuring biplane‐like building block, bicolumnar stacking water‐bridged networks, via overlap shells aligned boost superentropic driving force, distinguishable dual‐signals arises from emergence four types Pt‐Pt interactions, generating low‐energy metal‐to‐metal charge transfer adsorption/emission. addition, [Pt(CH ‐based hydrogel platform constructed for detecting cationic uranium, limit 14.89 fg. This work unlocks not only way detect but also idea sensing ions extreme layers.

Selenenylsulfide Bond as a General Scaffold for Constructing Thiol Probes with Enhanced Response Rate

Analytical Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Март 21, 2025

Leveraging disulfide (-S-S-) or diselenide (-Se-Se-) units as triggers in the design of small-molecule fluorescent probes for detecting intracellular reductive species has demonstrated high efficacy. However, selenenylsulfides, which exhibit reactivity between diselenides and disulfides, remain relatively unexplored. In this work, we compare efficiency -S-S-, seleno-sulfur (-Se-S-), sulfur-selenium (-S-Se-) structural constructing thiol probes, disclose scaffold -Se-S- a versatile recognition site thiols, successfully apply unit to near-infrared (NIR) probe, ASC-SeS. The mechanism reveals that breaking bond leads selenolate, undergoes faster cyclization than corresponding thiolate is from cleavage -S-S- -S-Se- bond. Conjugation trigger with multiple NIR fluorophores validates general applicability linear selenenylsulfides accelerating response rate thiols. By harnessing superior responsiveness ASC-SeS, employ probe live cells vivo, elucidate severe depletion thiols drug-induced liver injury (DILI).

A Fluorescent Probe for Convenient Visual Detection of Glyphosate Contamination in Water, Soil, and Vegetable Samples

Chemistry - An Asian Journal, Год журнала: 2025, Номер unknown

Опубликована: Апрель 28, 2025

Abstract Glyphosate, a widely used herbicide, has raised significant environmental and health concerns due to its persistence in food matrices. Accurate sensitive detection methods are essential for monitoring glyphosate contamination ensuring safety. In this study, fluorescent probe (DSG‐Cu[II]) been developed the selective of glyphosate. The fluorophore making is synthesized through reaction between dansyl chloride glycine, forming (DSG) capable binding copper ions (Cu[II]). resulting DSG‐Cu[II] complex functions via an “off‐on” fluorescence mechanism, wherein competitively displaces Cu[II], restoring fluorescence. This approach demonstrates high sensitivity rapid response, with limit 35 nM response time 30 s. Furthermore, was successfully applied real sample analysis, confirming practical applicability. Additionally, test strips incorporating enabled visual detection, highlighting potential on‐site monitoring. study presents efficient, selective, fluorescence‐based method contributing improved safety
