CuO nanoparticles produced by methods from inorganic chemistry and physics are applied as biocides and applications thereof in solar stills, solar collectors, catalysis, sensing and diesel fuels have been proposed. Such CuO nanoparticles are hazardous due to the release of Cu ions and the induced generation of reactive oxygen species after uptake b...

... studies will be briefly presented below. Table 1 compares the hazard of CuO nanoparticles coated with polyethylene glycol (PEGylated CuO nanoparticles), with the hazard of pristine CuO nanoparticles. Tatsi et al. [43] used CuO nanoparticles with polyethylene glycol, carboxylate and methylaminated compounds in 14 days toxicity tests with earthworms. ...Context 2
... series of papers regarding CuO nanoparticles coated with polyethylene glycol, carboxylate and methylaminated compounds ( [43,48,[53][54][55] did show that, for a specific coating, toxicities can differ substantially across species and components thereof. As indicated in Table 1, PEGylated CuO nanoparticles did in several cases show a lower toxicity than pristine CuO nanoparticles [43,54,55] but not in studies with Daphnia magna [53] and mussel lysosomes and haemocytes [48]. Tatsi et al. [43] also found that relative toxicities may differ in different environments (fresh and aged soil). ...Citations
