Fe3O4/HAP/Eu was designed for detection of LEV, whereas Fe3O4/HAP/Tb was developed for detection of CIP. The results showed that Fe3O4/HAP/Eu exhibited optimal excitation and emission wavelengths of 394 nm and 624 nm, respectively, with the fluorescence lifetime of 0.77 µs and the fluorescence quantum yield of 6.61%. Fe3O4/HAP/Tb performed optimal excitation and emission wavelengths of 370 nm and 551 nm, respectively, with the fluorescence lifetime of 1.06 µs and the fluorescence quantum yield of 8.28%. In terms of application, the linear range for detection of LEV was 1-50 µM, with detection limit of 0.67 µM. For CIP, linear range was 0.1-60 µM, and the detection limit was 0.086 µM. The two types of fluorescent composite provided reliable approach for detecting trace amounts of LEV and CIP in food.

Encountered exploration of novel carbon dots to manipulate the ray of light at a modest price. Nonetheless, a carbon dot suffers from a large spectral range detection of a ray of light, so the research has been devoted to exploring the materials to cover different spectral ranges. This article reports a novel dual-photon emissive carbon dot with large spectral emission coverage with an effortless preparation strategy. The rapid fabrication procedure constituted with dualcolour emissive carbon dots(MCCD) in a single solvent with utilization of biomass source. We have identified the mono-solvent effect induced dual emissive carbon dots observed in fluorescence spectroscopy. The fluorescence carbon particle displays the nature of excitation-independent behaviour, with an average granule size of 16.93 nm, result obtained via Transmission electron microscopy. The carbon structure suffered from the lower carbonization temperature with rapid microwave treatment, causing a turbostratic carbon structure. The dual colour contains with NIR region bright red emission solution tested against Z-scan non-linear properties, it exposes the excited state absorption involved in two-photon absorption. It offers an approach for optical limiting behaviour, with threshold reaches up to 0.53 × 10- 10 and 4.54 × 1012 W/m2 was observed for MCCD.

To facilitate disease monitoring and improve the understanding of related mechanisms, it is imperative to establish a rapid and precise method for detecting H2S. In this work, we have designed a new near-infrared fluorescent probe, designated TPA-YL, for H2S sensing. TPA-YL probe utilizes triphenylamine thiophene dye as a fluorophore, and 2,4-dinitrobenzenesulfonyl (DNS) as the response site for H2S. In the presence of H2S, the responsive group in TPA-YL undergoes thiolysis, and near-infrared fluorescence from the fluorophore is \"turned on\". The resulting fluorescence signal exhibits a good linear relationship with H2S up to 50 µM (limit of detection, 17 nM). The advantages of TPA-YL include: a long emission wavelength (642 nm); a large Stokes shift (188 nm); high selectivity; as well as remarkable sensitivity (under physiological conditions). Furthermore, the TPA-YL probe has been effectively applied for visualizing both externally supplied and internally generated H2S in HeLa cells via fluorescence imaging. Thus, this probe provides a promising strategy for studying the role of H2S in intricate physiological and pathological mechanisms. We develop a novel near-infrared fluorescent probe (TPA-YL) for the detection of H2S. In the presence of H2S, the responsive group in TPA-YL undergoes thiolysis, and near-infrared fluorescence from the fluorophore is \"turned on\". TPA-YL enables H2S detection in both in vitro and in vivo settings.","PeriodicalId":15800,"journal":{"name":"Journal of Fluorescence","volume":" ","pages":"1913-1921"},"PeriodicalIF":3.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145856723","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 main aim of the study was to explore how the surfactant-coated nanoparticle surface controls the binding and structural response of porcine serum albumin (PSA), acting here as the model protein. Synthesized C12-E2O2-C12-AgNPs were characterized by a spherical morphology, average size of 12.57 nm, and positive surface potential of + 19.50 ± 8.55 mV, confirming their stable dispersion. UV-Vis and fluorescence spectroscopic analyses revealed spontaneous and moderate binding of PSA to the nanoparticles, with the binding constants of 3.44 × 10⁴ M⁻¹ and 7.40 × 10⁴ M⁻¹, respectively. The interaction was mainly driven by electrostatic and hydrophobic forces, leading to changes in the secondary structure of PSA, as supported by FTIR and deconvolution of the amide I band. Surface tension studies further confirmed PSA-induced modulation of the interfacial property of the C12-E2O2-C12-AgNPst system, with a decrease in CMC and rise in molecular area (Amin), suggesting protein-mediated reorganization at the interface. Overall, these results offer new insights into the role of gemini surfactant-coated AgNPs in modulating protein-nanoparticles interactions relevant for biomedical and biosensing applications.","PeriodicalId":15800,"journal":{"name":"Journal of Fluorescence","volume":" ","pages":"2187-2207"},"PeriodicalIF":3.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146010650","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}
