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 key findings presented here provide valuable insights for researchers aiming to leverage TMDs in the development of next-generation sensor technologies, with a focus on optimizing sensitivity and selectivity.\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":"144751327","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 absorption spectrum of probe A did not show a significant change against analytes added to the solution. However, when the emission spectrum of probe A was examined, it gave two very low-intensity emissions at 400 nm and 540 nm. Probe A showed superior selectivity only for cyanide ions (CN−) with the limit of detection (LOD) of 1.42 nM in the presence of various competing analytes. This LOD value is the lowest value reported so far. For the first time, CN− sensing proceeds via benzoin condensation reaction. The stoichiometric ratio and detection mechanism between probe A and CN− were confirmed by Job's plot, HRMS, 1H-NMR, and FT-IR analyses. Probe A also worked successfully in the detection of CN−, which is a highly hazardous and toxic substance, including practical applications (three different real-world water samples).

In this study, we systematically investigated the binding interactions of DHEA with three biologically relevant targets: trypsin, calf thymus DNA (CT-DNA), and human serum albumin (HSA). 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. These findings highlight the multitarget potential of DHEA and support its relevance as a pharmacologically versatile molecule capable of modulating nucleic acids, transport proteins, and proteolytic enzymes.\u0000 </div>","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 8","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144740117","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 advancement of nanotechnologies has led to the emergence of metallic or metal oxide nanoparticles as potentially exciting resources. The unique features of zinc oxide (ZnO) nanorods make them very promising for a variety of tasks, such as gas detectors, diodes with light emission, solar panels, biological medicine, and solar energy generation. This investigation used biologically active substances from Dictyota dichotoma extracts to fabricate and encapsulate ZnO NRs, using zinc acetate dihydrate as the precursor. The novel bio-fabricated ZnO NRs have been tested for structural stability and optical variations using UV–Vis spectroscopy, FT-IR, XRD, FE-SEM, and EDX. Regarding Gram-positive, Gram-negative, and fungal strains, ZnO NRs have shown exceptional germicidal effectiveness. The MTT assay demonstrated the significant apoptotic efficacy of ZnO NRs against the HeLa cancer cell line. The ZnO NRs could eliminate around 90% of the photodecomposition against azo dye.

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.

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. This dual strategy solution-phase sensing and film-based detection with a portable device offers an efficient and practical approach for detecting nitroaromatic explosives in real-world settings.\u0000 </div>","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 7","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144681215","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}
