Limit of detection (LOD) was determined to be 1.43 nM for VB2 and 0.75 µM for Cr6+ (based on 3 s/k, LOD).

Addressing limitations like poor bioavailability and off-target effects of traditional chemotherapy, we engineered PDMS-CP1@1@Capecitabine nanoparticles. This novel formulation incorporates a gadolinium-based coordination polymer synthesized via a hydrothermal reaction with a thiourea Schiff-base ligand and embedded in a polydimethylsiloxane (PDMS) matrix, enhanced by the bioactive compound 1 from actinomycetes. Structural characterization demonstrated a crystalline nature with distinct XRD peaks at 21.4° and 25.6°, alongside remarkable fluorescence with peak emission at 444 nm and superior Fe3+ selectivity, showing 90% quenching efficiency against Fe3+ compared to other ions. These nanoparticles reduced CRC cell viability by up to 55% at 20 µg/mL, modulating USP22 and HSP90 expression, validated by molecular docking confirming hydrogen bonding interactions. PDMS-CP1@1@Capecitabine emerges as a potent targeted therapy for CRC, enhancing drug delivery and offering a novel approach for iron monitoring, pivotal for personalized treatment strategies.","PeriodicalId":15800,"journal":{"name":"Journal of Fluorescence","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143673647","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}

This extensive report presents a colorimetric probe, DPAB, for the identification of sarin mimic, diethylchlorophosphate (DCP) in both liquid and vapor phases. The initial yellow coloration of the DPAB solution gradually changes into a visible pink color due to the progressive accumulation of DCP, highlighting the effectiveness of DPAB as a colorimetric sensor. The characteristic pink coloration of the DPAB-DCP solution is completely reverted to the original yellow hue of free DPAB through the gradual and systematic introduction of triethylamine (TEA). The detection and quantification limit of DPAB is found to be in the nanomolar (nM) range. Additionally, we have developed a paper strip test kit as a practical application, enabling the immediate detection and measurement of DCP in actual threat situations. Furthermore, we also conducted experiments using dipstick and dip-vial conical flask to identify DCP vapor. The implementation of a smartphone-based readout technique facilitates the accurate measurement of DCP in isolated locations. Mechanistic aspects have been unveiled through density functional theoretical analysis. Our probe DPAB holds a promising candidate for environmental toxicology upon exposure to these hazardous nerve agents.","PeriodicalId":15800,"journal":{"name":"Journal of Fluorescence","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143673574","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}

In this regard, a new probe, N, N-dimethyl-4-(4-phenylquinazolin-2-yl) aniline (DAQ), was synthesized using microwave irradiation and characterized using various spectroscopic techniques. The crystal structure analysis revealed that DAQ crystallized in a monoclinic system with a P21/m space group. The probe exhibits fluorescence properties in solid state and solution, with positive solvatochromism observed as solvent polarity increased from hexane to DMF, indicating the existence of D-A structural units. The probe DAQ, exhibited reversible switching behaviour in the solution and solid state, indicating its sensitivity to volatile trifluoroacetic acid (TFA) and triethylamine (TEA) as confirmed by spectrophotometric and spectrofluorimetric studies. The binding constant of probe DAQ with TFA and TEA were studied by the Benesi Hildebrand (BH) plot using UV-Vis spectral titration. The estimated association constant was found to be 1.43 × 104 M- 1. The DAQ aggregation-enhanced emission properties have been successfully utilized to develop security ink and latent fingerprint information encryption on various substrates in their aggregated solid state. The study reveals that the sensitivity of DAQ warrants application on all forms of forensic evidence.","PeriodicalId":15800,"journal":{"name":"Journal of Fluorescence","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143670046","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}

This study investigates binding-induced Förster resonance energy transfer (FRET) between CQDs as donors and aflatoxin B1 (AFB1), a highly toxic mycotoxin, as the acceptor. Spherical CQDs, averaging 4.56 nm in diameter and emitting fluorescence at 455 nm, were synthesized for this purpose. Fluorescence spectroscopy, incorporating Stern-Volmer analysis and time-resolved lifetime measurements, revealed the critical role of FRET in this interaction. The estimated Förster radius (R0) of 4.81 nm and donor-acceptor separation distance (r) of 5.12 nm corresponded to a FRET efficiency of 46%. The observed decrease in donor fluorescence lifetime further supports the FRET mechanism. Selectivity experiments confirmed the system's specificity for AFB1 detection, with a limit of detection (LOD) of 0.439 nM. These findings underscore the potential of FRET-based CQD systems for sensitive and selective AFB1 detection, highlighting their versatility in fluorescence-based sensing applications and their promise for rapid food safety monitoring.","PeriodicalId":15800,"journal":{"name":"Journal of Fluorescence","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143663488","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}
