Bacterial Synthesis of Copper/Copper Oxide Nanoparticles
Journal of Nanoscience and Nanotechnology, 2008A bacterial mediated synthesis of copper/copper oxide nanoparticle composite is reported. A Gram-negative bacterium belonging to the genus Serratia was isolated from the midgut of Stibara sp., an insect of the Cerambycidae family of beetles found in the Northwestern Ghats of India. This is a unique bacterium that is quite specific for the synthesis of

Cytotoxicity and Genotoxicity of Copper oxide Nanoparticles in chickens
Biological Trace Element Research, 2021Copper oxide nanoparticles (CuO-NPs) are consciously used to control the growth of bacteria, fungi, and algae. Several studies documented the beneficial and hazardous effects of CuO-NPs on human cells and different experimental animals but there are not many studies that report the effect of CuO-NPs in poultry.

Genotoxicity of copper oxide nanoparticles in Drosophila melanogaster
Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2015Copper oxide nanoparticles (CuONPs) are used as semiconductors, catalysts, gas sensors, and antimicrobial agents. We have used the comet and wing-spot assays in Drosophila melanogaster to assess the genotoxicity of CuONPs and ionic copper (CuSO4). Lipid peroxidation analysis was also performed (Thiobarbituric Acid Assay, TBARS).

Characterisation of copper oxide nanoparticles for antimicrobial applications
International Journal of Antimicrobial Agents, 2009Copper oxide (CuO) nanoparticles were characterised and investigated with respect to potential antimicrobial applications. It was found that nanoscaled CuO, generated by thermal plasma technology, contains traces of pure Cu and Cu2O nanoparticles. Transmission electron microscopy (TEM) demonstrated particle sizes in the range 20-95 nm.

Oxygen Plasma Generated Copper/Copper Oxides Nanoparticles
The Journal of Physical Chemistry B, 2004Oxygen-plasma-generated CuOx nanoparticles enhanced the carriers injection from indium−tin oxide (ITO) anode into organic materials. Atomic force microscopy images revealed that the CuOx nanoparticles appeared as high-ordered nanotip arrays on substrates. Those nanoparticles induced strong field-emission current.
