Carbon Quantum Dots/Titanium Dioxide (CQDs/TiO₂) Nanocomposites were reported as potent compounds against SARS-COV-2. In this manuscript, citric acid is the carbon precursor used to synthesize carbon quantum dots (CQDs). Using a green approach, the synthesized CQD fabricates the Carbon Quantum Dots/Titanium Dioxide (CQDs/TiO2) Nanocomposites. Synthesized composites were characterized by using a UV–visible spectrophotometer, Fourier-transformed infrared (FTIR) spectrometry, X-ray diffractometry (XRD), and Scanning electron microscopy with energy dispersive X-ray analysis (SEM–EDX). Methylene blue was used to check the Photocatalytic activity of synthesized (CQDs/TiO₂) nanocomposites of different concentrations. Computational modeling of agglomerates of CQD and TiO2 nanoparticles with the formula TiO₂…….. Ti₂₅₃O₅₀₆ demonstrated two stages of the nanocomposite formation, including the formation of agglomerates with the neutral and salt-like structures with the total gain in the Gibbs free energy − 38.397 kcal/mole. In silico, Molecular docking studies of citric acid were evaluated against SARS-COV-2 protein to understand their mechanism and key amino acid interactions along with standard drug remdesivir. The photocatalytic activity of CQDs/TiO₂ showed extremely promising results. Based on this study, the proposed mechanism of action of these compounds is reported. A detailed investigation of CQDs/TiO₂ against SARS-CoV-2 is needed, which is another part of the research in our next manuscript.</p></div>","PeriodicalId":51136,"journal":{"name":"Nanoscale Research Letters","volume":"19 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s11671-024-04117-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142761824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among them, ZEB1-AS1 was identified as an upregulated candidate in HNSC through comprehensive analysis of RNA-sequencing datasets. Here, elevated ZEB1-AS1 expression was correlated with poor prognosis in HNSC patients. Further investigations demonstrated that downregulation of ZEB1-AS1 induced epithelial-mesenchymal transition and increased sensitivity to cisplatin in Cal27 cells, while its upregulation reversed these effects, underscoring its pivotal role in tumor metastasis and cisplatin resistance in Cal27 cells. Mechanistically, ZEB1-AS1, located in cytoplasm and nucleus, directly regulated the expression of ZEB1, thereby influencing the expression of μ opioid receptor (MOR) and implicating in cancer progression. To advance clinical translation, we employed a nucleus-targeting nanoparticle platform for efficient delivery of a mixture of antisense oligonucleotides and siRNA (Silencer), effectively manipulating ZEB1-AS1 expression in vitro and in vivo. Besides, a predictive model for HNSC patients was developed by analyzing the expression levels of ZEB1-AS1, ZEB1, and MOR in the HNSC datasets.

Different characterization techniques such as UV-vis spectroscopy, dynamic light scattering, Fourier Transform Infrared Spectroscopy, Field emission scanning electron microscope, High resolution transmission electron microscopy, and X-ray diffraction were employed to check the production of SP-AgNPs.

SP-AgNPs exhibited significant catalytic activity in the decomposition of various pollutants such as Methyl Orange (0.035 ± 0.090 min⁻¹, 92.89 ± 1.79%), Crystal Violet (0.1097 ± 0.1016 min⁻¹, 85.56 ± 2.21%) and Cosmic Brilliant Blue G-250 (0.0697 ± 0.0275 min⁻¹, 79.56 ± 1.80%).
