Copper oxide nanoparticles (CuO-NPs) have been increasingly released in aquatic ecosystems over the past decades as they are used many applications. Cu toxicity to different organisms has already highlighted literature, however mechanisms of nanoparticulate form remain unclear. Here, we investigated effect, transfer and localization CuO-NPs compared salt on plant Myriophyllum spicatum, an ecoto...

The antimicrobial properties of CuO nanoparticles have been investigated, but the underlying mechanisms of toxicity remain the subject of debate. Here, we show that CuO nanoparticles exhibit significant toxicity at pH 5 against four different Staphylococcus aureus (S. aureus) strains, including Newman, SA113, USA300, and ATCC6538. At this pH, but not at pH 6 and 7, 5 mM CuO nanoparticles effect...

Two Cu-Co and Co3O4 oxides were synthesized by the conventional sol-gel auto-combustion and their physical-chemical properties were characterized by XRD, FTIR, SEM, TPR and XPS. The XRD results indicated that copper-cobalt oxide appeared in a mixture form of Cu0.15Co2.85O4 spinel and CuO phases, whereas the cobalt oxide exhibited in the pure form of Co3O4 spinel. The FTIR approved the formation...

The Pipper nigram (P. nigram) leaf extract was used for the biosynthesis of copper oxide nanoparticles (CuO NPs) and successful formation resultant product confirmed through several physicochemical techniques. chemical structure elemental composition were analysed Fourier transform infrared (FTIR) energy dispersive X-ray (EDX) spectroscopies, respectively. crystalline crystallite size investiga...

2010 WILEY-VCH Verlag Gmb The synthesis of colloidal nanoparticles (NPs) possessing hollow or core/shell structures has attracted a great deal of attention because these materials exhibit unique physical and chemical properties that allow them to be used in catalysis and drug delivery. These particles are typically produced using sacrificial templates, such as polystyrene or silica. Nevertheles...

20 The global analysis of the cellular lipid and protein content upon exposure to metal and metal oxide 21 nanoparticles (NPs) can provide an overview of the possible impact of exposure. Proteomic analysis has 22 been applied to understand the nanoimpact however the relevance of the alteration on the lipidic profile 23 JOURNAL OF INTEGRATED OMICS A METHODOLOGICAL JOURNAL HTTP://WWW.JIOMICS.COM ...

CuO nanoparticles with an average size of ca. 4 nm have been successfully prepared by microwave irradiation, using copper (II) acetate and sodium hydroxide as the starting materials and ethanol as the solvent. The CuO nanoparticles are characterized by using techniques such as X-ray powder diffraction, transmission electron microscopy, selected area electron diffraction, X-ray photoelectron spe...

In this study, the effects of treatment with Ag, Au, Cu, Pd, CeO2, CuO, TiO2 and ZnO nanoparticles (NPs) on plant secondary metabolism were tested using an untargeted metabolomic approach in cell suspension cultures Hypericum perforatum L. Variations accumulation metabolites observed after exposure to NPs. Overall, number compounds increased by metal NPs was higher than that oxides. Among oxide...

The reduction of CuO dispersed on ̄uorite-type oxide catalysts, namely La-doped CeO2 and Y-doped ZrO2 was studied in this work. On both supports distinct copper species were identi®ed as a function of copper content by temperatureprogrammed reduction (TPR) by H2 and CH4, X-ray photoelectron spectroscopy (XPS), X-ray powder diffraction (XRD) and scanning transmission electron microscopy/energy d...

This study aims to provide an updated survey of the main synthesis methods of copper oxide (CuO) nanoparticles in order to obtain tailored nanosystems for various biomedical applications. The synthesis approach significantly impacts the properties of such nanoparticles and these properties in turn have a significant impact on their biomedical applications. Although not widely investigated as an...
