Copper oxide (CuO) nanoparticles (NPs) are abundant in manufacturing processes, but they an airway irritant. In vitro pulmonary toxicity of CuO NPs has been modeled using cell lines such as human bronchial epithelial line BEAS-2B. 2D culture, BEAS-2B undergoes squamous differentiation due to the presence serum. Differentiation is part repair process lung cells vivo that helps preserve lining re...

Abstract In this study, copper oxide nanoparticles (CuO NPs) were green synthesized using the leaf extract of Momordica cochinchinensis (Lour.). Various characterization techniques such as Energy-dispersive x-ray spectroscopy (EDS), Ultraviolet Visible (UV–vis) Spectroscopy, diffraction (XRD), Transmission Electron Microscopy (TEM) and Fourier-transform Infrared (FTIR) Spectroscopy utilized to ...

In the last few decades, use of copper oxide nanoparticles (CuO NPs) has been increased significantly that eventually included as a growth stimulator. This makes it essential to examine their impact on several plants. study detailed here, we investigated effects CuO NPs growth, physiological efficiency, biochemical assays, and antioxidant system in mustard plant. Varying concentrations (0, 2, 4...

Abstract This work showed the preparation of Copper oxide nanoparticles (CuO NPs) from leaf extract Cinnamomum camphora (C.camphora) by a green synthetic method. To prepare CuO NPs, about 10 ml 0.01 M copper sulphate and 30 C.camphora were mixed heating for 60 min at temperature 80 °C. Various techniques such as x-ray diffraction analysis (XRD), Energy-dispersive spectroscopic (EDS), Fourier-tr...

Nanotechnology is a field that, over the years, has been growing in several research areas, such as medicine, agriculture and cosmetics, among others. As result, there continuous increase production, use disposal of these materials environment. The behaviour (bio) activity atmosphere, water soil are not fully studied. Therefore, it necessary to carry out an analysis risks contamination, well po...

The toxic effects of individual and binary mixtures of five metal oxide nanoparticles (NPs) were evaluated based on changes in two endpoints of algal growth: the cell count and chlorophyll content. Various effects were observed according to the concentration tested and type of NPs, and there were no significant differences in findings for the two endpoints. In general, ZnO NPs caused the greate...

A clear understanding of physicochemical factors governing nanoparticle toxicity is still in its infancy. We used a systematic approach to delineate physicochemical properties of nanoparticles that govern cytotoxicity. The cytotoxicity of fourth period metal oxide nanoparticles (NPs): TiO2, Cr2O3, Mn2O3, Fe2O3, NiO, CuO, and ZnO increases with the atomic number of the transition metal oxide. Th...

This work makes an investigation of Polyvinyl Alcohol (PVA)/Polyvinyl Pyrrolidone (PVP) composite scattered by copper oxide nanoparticles. Spectroscopic techniques have been utilized for studying the mechanism reaction between PVA/PVP and CuO NPs. Cell viability antibacterial assessment are used investigating activity nanocomposite systems. XRD FTIR-ATR approved complexation miscibility PVA, PV...

The preparation of trans-dihydrofurans has been achieved by a one-pot condensation reaction of 4-bromophenacyl bromide, aromatic aldehydes and 5,5-dimethyl-1,3-cyclohexanedione using biosynthesized CuO nanoparticles under reflux conditions in ethanol. CuO nanoparticles (CuO NPs) were prepared using extractof leaves of Ajuga chamaecistus Subsp. Scoparia. The key advant...
