To accurately monitor mitochondrial viscosity changes, a novel fluorescent probe called DWL-IY was developed by using the twisted intramolecular charge transfer (TICT) mechanism. The probe DWL-IY demonstrated high selectivity for viscosity and good photostability under both light and light-avoidance conditions. It also showed high sensitivity, with the fluorescence intensity increasing by 146-fold from methanol to glycerol and a large Stokes shift of 77 nm in methanol and 85 nm in glycerol.

In this research, the interaction mechanism between AO and α-glucosidase was investigated using UV–Vis, fluorescence analysis, FT-IR, circular dichroism (CD), and molecular docking techniques. AO induced static quenching of the fluorescent groups in α-glucosidase through a spontaneous reaction process (ΔG0 < 0), primarily driven by hydrogen bonds and van der Waals forces at a single binding site. The interaction between AO and α-glucosidase resulted in a reduction of the α-helix content while increasing the β-turn and random coil components within the secondary structure of α-glucosidase. A detailed analysis of molecular docking results revealed that AO interacted with Tyr158 and Tyr316 residues in α-glucosidase, leading to fluorescence quenching of the enzyme and enhancing the hydrophobicity surrounding these tyrosine residues. Furthermore, AO formed hydrogen bonds with Glu277, Arg315, Asn415, and Arg442 while generating van der Waals interactions along with hydrophobic forces involving Phe159 and other amino acid residues. Through these intermolecular interactions, AO bound to the active center's binding cavity in α-glucosidase, resulting in conformational changes that ultimately affect enzymatic activity.\u0000 </div>","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 6","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144171641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The synthesized material, denoted as CsPbBr3@ZIF-8, was fabricated with ultrafine CsPbBr3 perovskite particles having an average radius of 5 nm. Benefiting from the outstanding optical properties and remarkable water stability of CsPbBr3@ZIF-8, a fluorescent quenching-based sensing platform for the detection of Hg2+ ions in aqueous solutions has been established.

This conclusion was drawn by comparing the discrepancies in the fluorescence lifetimes of CsPbBr3@ZIF-8 before and after the introduction of Hg2+ ions.
