The fluorescence intensity of fluorescein was quenched upon interaction with sulfasalazine. This quenching effect was observed at an emission wavelength of 513 nm, with excitation at 492 nm. A calibration curve constructed between the fluorescence intensity and sulfasalazine concentration exhibited a linear relationship over the range of 1-45 μg/mL, with an excellent correlation coefficient of 0.994. The method demonstrated a limit of detection (LOD) of 2.64 × 10-2 μg/mL and a limit of quantification (LOQ) of 8.82 × 10-2 μg/mL. Common pharmaceutical excipients were tested and found to have no significant interference with the measurement of sulfasalazine. The proposed method was successfully applied to the analysis of sulfasalazine in pure form, commercial pharmaceutical formulations, and biological fluids. The percentage recovery ranged from 97.05% to 103.54%. Fluorescence quenching was analyzed using the Stern-Volmer equation.

Hence, the development of persistent luminescence phosphors capable of excitation under blue light is of critical importance. Bright green light Ca8−xMg3AlGaSi7O28:x%Eu2+ phosphors were synthesized by the high-temperature solid-state reaction method. After Rietveld refinement, the results showed that Rwp = 7.85%, Rp = 5.36%, χ2 = 2.12. The space group of the Ca8Mg3AlGaSi7O28 structure is P-421 m. Ca2+ is surrounded by 8 O2− ions, forming a Cs point-symmetric CaO8 polyhedron. Ca2+ and Eu2+ share their crystal structure sites and connect eight O2− to form Ca/EuO8. Based on the diffuse reflectance spectrum, the optical band energy (Eg) value for CMAGSO:0.1%Eu2+ was calculated to be approximately 4.02 eV. The presence of only one broad peak between 35°C and 150°C in the thermoluminescence spectra indicates that there is only one trap in these samples. Through calculation, it can be known that the depth of the trap is between 0.65 and 0.66 eV. The prepared phosphor materials have good application prospects in security and emergency response systems, information encryption, anti-counterfeiting.\u0000 </div>","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 8","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144758577","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}

Moreover, the PL quantum yield (41.7%) of the composite nanospheres was higher than that of the pure complex powders (38.4%), which suggested these composite nanospheres were more suitable for visualization and detection of latent fingerprints (LFPs). Using them as the luminescent developer, the fingerprint patterns developed from LFPs on both nonporous and porous surfaces all showed high brightness and contrast under 365nm UV light, and the first-, second-, and third-level details were all clearly distinguished, especially on nonporous surfaces.\u0000 </div>","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 8","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144751329","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}

It focuses on categorizing the mechanisms involved, such as chemiresistive, field-effect transistor (FET), surface-enhanced Raman scattering (SERS) and piezoresistive methods, which illustrate the sensor functionalities of TMDs. The review emphasizes the importance of several properties like charge transfer processes, surface interactions and structural dynamics. The interaction between TMDs and target molecules leads to necessary modifications that influence the sensor's output signal, including defect formation, doping effects and bandgap adjustments (ranging from 1 to 2 eV). Additionally, the review investigates other critical parameters that enhance sensor performance, like the number of TMD layers, functionalization methods and various chemical and physical environments. These factors can significantly improve selectivity by up to 200% and decrease response times to just a few milliseconds. To further enhance the sensitivity, selectivity and stability of TMD-based sensors, reproducibility and other relevant parameters are also discussed in light of recent advancements.

The effects of DHEA on the structure and activity of these macromolecules were carried out using fluorescence spectroscopy, FTIR, and molecular docking techniques. Molecular docking simulations revealed that DHEA forms stable complexes with all three macromolecules, exhibiting the highest affinity toward HSA (−8.71 kcal mol−1), followed by trypsin (−6.30 kcal mol−1) and DNA (−6.15 kcal mol−1). DHEA was found to bind within the minor groove of DNA through hydrogen bonds and van der Waals interactions, occupy Subdomain IB of HSA stabilized by hydrophobic contacts, and interact near the catalytic triad of trypsin through alkyl and π–alkyl interactions. In silico ADMET profiling predicted favorable drug-like properties, including high gastrointestinal absorption, blood–brain barrier permeability, and low toxicity risk.
