This contribution reports an ecological benevolent route for the fabrication of copper oxide nanoparticles (CuONPs) using Leucaena leucocephala L. leaves extracts at room temperature. Phytochemical screening of the fresh aqueous leaves extract showed the presence of tannins, saponins, coumarins, flavonoids, cardial glycosides, steroids, phenols, carbohydrates and amino acids. Copper oxide parti...

Nanobiotechnogy has been developed to synthesized copper oxide nanoparticle. This was carried out biologically using leaf extract of Psidium guajava as a reducing and stabilizing agent. Optical property showed color change from dark brown gold- yellow after the addition extract. The possible functional group in plant responsible for reduction CuONps identified belonging alkyl halide by FT-IR an...

Abstract Nanoparticles are known bio elicitors in plant biotechnology. Different concentrations of ZnO, CuO and CoO nanoparticles were used for the enhanced accumulation secondary metabolites antioxidant activities callus derived from root, shoot leaf Artemisia annua L. Biomass was somehow affected on high Nps. Phenolic content observed maximum (60µg) at 0.1mg/l CuONps. Total activity (33µg) ro...

conclusions the nps-induced ots may increase the pro-inflammatory responses. on the other hand, administration of antioxidants such as nac and vitamin c and e prior to exposure to metal nps significantly decreases ots conditions. evidence acquisition here, a nanotechnology approach is evaluated using nps in human neuronal protection against ots. it may be wide therapeutic applications in the ca...

In this paper, CuO nanoparticles are synthesized using Tilia platyphyllos extract as reducing and stabilizing agents and TiO2are prepared via facile sol-gel method as an ideal support. FT-IR spectroscopy, UV-Vis spectroscopy, X-ray Diffraction (XRD), Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray Spectroscopy (EDS), and Transmission Electron Microscopy (TEM) were used to characte...

Copper Oxide Nanoparticles (CuONPs) show a broad spectrum of antimicrobial activity against various species microorganisms, including gram-positive and gram-negative fungi bacteria, but in general bacteria are more resistant to the effects copper nanoparticle ions than ones. In this work, synthesis oxide nanoparticles has been carried out using laser ablation methods were applied as antibacteri...

Recent attention has been drawn to green methods for preparing metal oxide nanoparticles due their ease of preparation and environmental friendliness in comparison with chemical physical methods. By using an eco-friendly reducing agent, Pimpinella anisum seed extract, this study describes a method synthesizing CuO that are based on biological principles. Copper were produced utilizing precipita...
