To improve the sensitivity and specificity of imaging techniques, researchers are increasingly turning to nanomaterials as contrast agents. Among them, upconversion nanoparticles (UCNPs) stand out for their ability to convert near-infrared (NIR) light into visible emission. This property enables deep tissue penetration, reduced autofluorescence, and low phototoxicity. We report the synthesis of LaF3 codoped with 2 mol% Er3+ and 20 mol% Yb3+ using a hydrothermal method, followed by surface modification with human serum albumin (HSA). Structural analysis confirms the formation of rhombohedral LaF3 with uniform dopant incorporation, and electron microscopy reveals a near-spherical morphology with average particle sizes increasing from ~25 nm (bare) to ~60 nm (HSA-coated). Under 976-nm excitation, the nanophosphors exhibit bright green and red UC emissions via a two-photon mechanism. Cytotoxicity studies demonstrate high cell viability at concentrations up to 0.4 mg/mL in HeLa cells, while fluorescence uptake assays indicate time-dependent internalization, peaking at 6-h post-treatment. These findings highlight the potential of HSA-coated LaF3:Er3+,Yb3+ nanophosphors as efficient, biocompatible contrast agents for NIR-excited luminescent bioimaging.","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 7","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bio.70269","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144695805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Trinitrophenol (TNP), a highly toxic and explosive compound, requires urgent monitoring. In this work, a novel benzimidazole-based covalent triazine framework, CTF TFPOT-BTA, was synthesized via solvothermal condensation of 1,2,4,5-benzenetetraamine tetrahydrochloride and 2,4,6-tris(4-formylphenoxy)-1,3,5-triazine. The resulting CTF exhibited excellent selectivity towards TNP, with a low detection limit of 1.38 nM and a linear detection range from 32.15 × 10−7 to 4.6 × 10−5 M. Fluorescence quenching was attributed to a combination of inner filter effect (IFE), Förster resonance energy transfer (FRET), and photoinduced electron transfer (PET) mechanisms. To enhance practical usability, a fluorescent film was developed by incorporating the CTF into a polyvinyl alcohol (PVA) matrix. The resulting CTF-PVA film showed high flexibility, water stability, and a fast fluorescence quenching response upon TNP exposure. Furthermore, a portable device was designed for rapid and user-friendly detection of TNP based on fluorescence quenching.

Herein, a colorimetric/fluorescent dual-mode sensor based on rhodamine B–aluminum complex (RhB–Al3+) has been developed for the detection of trace water in methanol, ethanol, isopropanol, and 1-butanol. The RhB–Al3+ complex demonstrates rapid response (< 10 s), high sensitivity (detection limits [v/v]): 0.0134% (ethanol), 0.0074% (methanol), 0.0224% (isopropanol), and 0.0498% (1-butanol), and excellent specificity. In addition, the color of the RhB–Al3+ complex in alcohols solution changed from pink to colorless under visible light and from yellow to colorless under a 365-nm UV light, which enabled naked-eye detection of trace water in alcohol solvents. The sensing mechanism was investigated by 1H-NMR, HR-MS, pH, and spectroscopy analysis. It was demonstrated to involve water molecules coordination to the Al3+ of the RhB–Al3+ complex, which leads to the dissociating of the complex and in turn promotes the reformation of the rhodamine spirolactam ring.
