Catalysts, Journal Year: 2023, Volume and Issue: 13(2), P. 215 - 215

Published: Jan. 17, 2023

As a result of the sol-gel method, we were able to produce pure ZnO and ZnO-doped TiO2 nanocomposites. The hexagonal wurtzite phase in products was discovered by powder X-ray diffraction (XRD). are typically crystallites, formed according Debye Scherrer formula. Nanocomposites with significant morphological changes created using process, including those that resembled rocks. To determine composition Zn, O, Ti atoms samples, multidimensional analysis performed. There is an energy gap between 3.61 eV, as determined UV-vis spectroscopy. In this study, nanocomposites used study degradation methylene blue (MB) under visible light irradiation. Over irradiation course 6 h, composite (84%) studied. kinetic analysis, made from followed pseudo-first-order kinetics. presence nanocomposites, antibacterial activity significantly improved. This shown be effective against Gram-positive Gram-negative bacteria (Escherichia coli B. sublittus). evidence metal oxide produced can appropriate antimicrobial disinfection alternative, particularly biomedical settings, reported more detail.

Arabian Journal of Chemistry, Journal Year: 2023, Volume and Issue: 16(10), P. 105192 - 105192

Published: July 26, 2023

Although zinc oxide nanoparticles (ZnO NPs) have demonstrated promising anticancer activity, their therapeutic performances are frequently influenced by the synthesis routes and associated distinct physicochemical characteristics. Herein, ZnO NPs were synthesized through a cost-effective flame spray pyrolysis-assisted approach selective effects underlying intrinsic apoptosis signaling pathway in human gastric carcinoma cell line (AGS) examined. Transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), dynamic light scattering (DLS) investigations used to characterize NPs. Afterwards, AGS normal fibroblast cells (L-929) treated with various concentrations of NPs, proliferation was examined MTT assay determine IC50 concentration Furthermore, quantification ROS done fluorometer flow cytometry assays. Additionally, superoxide dismutase (SOD) catalase (CAT) activity assays performed evaluate oxidative stress-induced cytotoxicity mediated against cells. Moreover, caspase-3/-8/-9 mitochondrial membrane potential (MMP) done.
