In this study, an aqueous extract of <i>Nyctanthes arbor-tristis</i> leaves was used to synthesize NL-ZnONPs, and their various biological applications were assessed. The maximum absorbance (λmax) of NL-ZnONPs was found at 376 nm. SEM and XRD analyses confirmed the amorphous nature of the NL-ZnONPs, while FTIR analysis revealed that phytochemicals from the plant extract capped the surface of the NL-ZnONPs. NL-ZnONPs inhibited mammalian α-glucosidase activities-maltase, sucrase, isomaltase, glucoamylase-, and α-amylase activity through non-competitive inhibition, with IC<sub>50</sub> values of 594.4 ± 1.79 µg/mL, 1160.2 ± 4.8 µg/mL, 648.4 ± 3.6 µg/mL, 719.3 ± 2.3 µg/mL, and 398.4 µg/mL, respectively.

Additionally, NL-ZnONPs exhibited antibacterial activity against <i>Klebsiella pneumoniae</i>, <i>Staphylococcus aureus</i>, <i>Escherichia coli</i>, and <i>Candida parapsilosis</i> at a concentration of 100 µg/mL.

We assessed the cancer prevention characteristics of the biosynthesized bimetallic CuO-ZnO nanocomposites. Characterization of the CuO-ZnO BMNCs was performed using various techniques, with UV-Vis, FTIR, zeta potential, DLS, EDX, and SEM analyses. This investigation demonstrates the synthesis process, distinctive properties, antioxidant activity, and anticancer mechanisms of the nanocomposites, as well as their potential therapeutic applications. The UV–visible spectrum of CuO-ZnO BMNCs exhibited an absorption peak at 370 nm, confirming the formation of CuO-ZnO nanocomposites. The XRD analysis revealed the crystalline nature of the BMNCs, while SEM images demonstrated predominantly spherical particles with an average diameter of 119 nm. The impacts of CuO-ZnO BMNCs on HeLa cells were examined through cell viability, ROS activation, and apoptosis induction. The cell death was measured with an Annexin V-fluorescein isothiocyanate assay, and cell cycle impact was evaluated by staining DNA with propidium iodide. Time-dependent cell death was observed with BO-Cu/ZnO BMNCs, showing a maximum inhibitory effect of 49 ± 1.34% at doses of 15 µg/mL or higher after 24 h of treatment.

In the current study, we investigate the development of Zr metal-organic framework (MOF) UiO-66 nanoparticles coated with folic acid-conjugated polyethylene glycol (UIO-66-EPI@PEG-FA) as a targeted delivery of Epirubicin (EPI) to breast cancer cells. A significant encapsulation efficiency was seen in the UIO-66-EPI@PEG-FA nanoparticles (75.33 ± 1.34%). The patterns of drug release demonstrated the pH-dependent behavior of the nanoparticle, with a release of approximately 62.6% at acidic pH (5.4) over 24 h, compared to 47.2% at physiological pH (7.4). As evidenced by flow cytometry results, apoptosis rate induced in MCF-7 cells by UIO-66-EPI@PEG-FA (40.9%) was found to be higher than that induced by free EPI (23.03%). Furthermore, wound healing assay showed that UIO-66-EPI@PEG-FA successfully inhibited cell migration, consolidating its role in preventing cancer progression. As evidenced by polymerase chain reaction (PCR) assay, by decreasing the MMP-2 and MMP-9 genes’ expression levels as well as significant upregulation of pro-apoptotic markers (caspase-3, caspase-9, and mitofusin-1), the UIO-66-EPI@PEG-FA inhibited the growth of the malignancy by activating both intrinsic and extrinsic apoptotic pathways. DAPI-stained microscopy verified the flow cytometry study’s results, showing that the produced nanoparticle successfully induced death in cancer cells.

The physicochemical characteristics of these spent adsorbents were studied using XRD, UV-Vis and XPS spectroscopy, potentiometric titration and adsorption-desorption of nitrogen. It was established that the introduction of these cations into the clinoptilolite skeleton by ion exchange does not lead to the formation of a separate metal phase, but contributes to the formation of a meso-macroporous structure and the narrowing of the band gap (doping effect). As a result, such doped clinoptilolites have a higher photocatalytic activity under visible irradiation compared to the initial clinoptilolite, which is minimally active due to the presence of iron impurity. Therefore, a facile way of using the spent clinoptilolite adsorbents for photocatalytic degradation of organic pollutants of water under visible illumination is proposed. The novelty of the obtained results is manifested in two aspects: scientific—the photocatalytic activity of clinoptilolites with a low content of doping transition metals (0.3–0.5%) under the action of visible irradiation, and practical—the possibility of using spent clinoptilolite cation exchangers for water purification from pollutants.</p></div>","PeriodicalId":618,"journal":{"name":"Journal of Cluster Science","volume":"36 2","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143108272","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}
