objective(s): this study aimed to determine the possible toxicity of cuo nanoparticles (nps) on oncorhynchus mykiss by evaluating hematological parameters.materials and methods: fish were sampled and treated in 4 aquariums containing the concentration ranges of 1, 5, 20 and 100 ppm of cuo nps. there was one control group (no cuo nps) and three replicates. the physicochemical properties of water...

Metal oxide nanoparticles, such as copper oxide (CuO), are mass produced for use in a variety of products like coatings and ceramics. Acute exposure to CuO nanoparticles has caused toxicity to many aquatic organisms, yet there is no information on the effect of prolonged CuO nanomaterial exposures. This study examined effects of chronic exposure to CuO nanoparticles on Xenopus laevis growth and...

The present study investigated the effects of exposure to metal oxide nanoparticles on vasculogenesis/angiogenesis using transgenic zebrafish. The study also examined the potential mechanisms involved in those effects using human umbilical vein endothelial cells (HUVEC). TG (nacre/fli1:EGFP) zebrafish were exposed to nano-sized titanium dioxide (TiO2), silica dioxide (SiO2), and copper oxide (C...

Copper oxide (CuO) nanoparticles (NPs) were decorated on reduced graphene (rGO) through the effective synthetic route method. Powder X-ray diffraction, Fourier transform infrared, ultraviolet-visible absorption, and scanning electron microscopy techniques used to analyze chemical structure, functional groups, absorbance, morphology. Under visible light illumination, CuO/rGO nanocomposites have ...

Metal oxide nanoparticles (NPs) have been widely used in industrial and agricultural production introduced into soils. The impact of these on soil nitrous (N2O) emission is unclear. We conducted a microcosm experiment to investigate the effects titanium (TiO2 NPs), copper (CuO aluminum (Al2O3 NPs) N2O emissions abundance functional genes related production/reduction. Compared without NPs additi...

in the present study, tenorite (cuo) nanoparticles have been assayed for their catalytic properties. the decontamination reaction of chloro ethyl ethyl sulfide (cees) as an surrogate of sulfur mustard simulant have been accomplished on the surface of cuo nps with different weight ratios at ambient temperature and monitored by gas chromatography equipped with flame ionization detector (gc-fid) a...

Submit Manuscript | http://medcraveonline.com treating these and other bacterial infections currently exist; there is still an essential need for new and improved approaches for bacterial destruction. Nanomedicine is one approach to overcome challenges of conventional drug delivery systems based on the development and fabrication of nanostructures. Various types of nanoparticulate systems have ...

Environmentally friendly copper oxide nanoparticles (CuO NPs) were prepared with a green synthesis route via Anchusa strigosa L. Flowers extract. These further characterized by FTIR, XRD and SEM techniques. Removing of Gongo red from water was applied successfully using synthesized CuO NPs which used as an adsorbent material. It validated that the eliminate Congo means adsorption, best efficien...

The Caspian trout is an endangered and quite vulnerable fish, considered for a natural protection program in the southern area of the Caspian Sea. Copper oxide nanoparticles (CuO-NPs) are toxic substances, which induce oxidative stress, not to mention other pathophysiological states. The toxicity of nanoparticles on fish needs more characterization for short- and long-term effects.  Thus, the p...

a facile mechanochemical-based method for synthesis of copper oxide (cuo) nanoparticles is here by introduced. for this purpose, copper hydroxide powder was synthesized through a facile solution method (cuso4 + 2 na(oh) → cu(oh)2 + na2so4) after which milling of as-prepared cu(oh)2 precursor and nacl resulted in the mechanochemical dehydration of cu(oh)2 and dispersion of cuo nanoparticles into...
