CuO nanostructures: Synthesis, characterization, growth mechanisms, fundamental properties, and applications
Qiaobao Zhang,Kaili Zhang,Daguo Xu,Guangcheng Yang,Hui Huang,Fude Nie,Chenmin Liu,Shihe Yang +7 more
TL;DR: A comprehensive review of recent synthetic methods along with associated synthesis mechanisms, characterization, fundamental properties, and promising applications of Cupric oxide (CuO) nanostructures is presented in this article.
Journal ArticleDOI
Toxicity of Ag, CuO and ZnO nanoparticles to selected environmentally relevant test organisms and mammalian cells in vitro: a critical review
Olesja Bondarenko,Katre Juganson,Katre Juganson,Angela Ivask,Kaja Kasemets,Monika Mortimer,Monika Mortimer,Anne Kahru +7 more
TL;DR: The toxic range of all the three metal-containing NPs to target- and non-target organisms overlaps, indicating that the leaching of biocidal NPs from consumer products should be addressed.
Journal ArticleDOI
Ecotoxicity of manufactured ZnO nanoparticles – A review
TL;DR: These studies suggest relative high acute toxicity of ZnO NPs (in the low mg/l levels) to environmental species, although this toxicity is highly dependent on test species, physico-chemical properties of the material, and test methods.
Journal ArticleDOI
From ecotoxicology to nanoecotoxicology.
TL;DR: This review evaluated the currently existing literature data on toxicity (L(E)C50 values) of synthetic NPs in environmentally relevant species to identify tentatively most harmful NPs and most sensitive organism groups, and to provide relevant ecotoxicological information for further risk assessment.

Toxicity of ZnO Nanoparticles to Escherichia coli: Mechanism and the Influence of Medium Components
Mei Li,Lizhong Zhu,Daohui Lin +2 more
TL;DR: Water chemistry can be a major factor regulating the toxicity mechanism of ZnO nanoparticles (nano-ZnO) in water and the effect of water chemistry on the physicochemical properties of nanoparticles should be paid more attention in future nanotoxicity evaluations.

TL;DR: A review with 156 refs on interfacial electron transfer reactions in colloidal semiconductor solns and thin films and their application for solar light energy conversion and photocatalytic water purifn is presented in this paper.
Journal ArticleDOI
Toxicity of nanosized and bulk ZnO, CuO and TiO2 to bacteria Vibrio fischeri and crustaceans Daphnia magna and Thamnocephalus platyurus.
TL;DR: This is the first evaluation of ZnO, CuO and TiO2 toxicity to bacteria Vibrio fischeri and crustaceans Daphnia magna and Thamnocephalus platyurus with a special emphasis on product formulations (nano or bulk oxides) and solubilization of particles.
Journal ArticleDOI
Comparative eco-toxicity of nanoscale TiO2, SiO2, and ZnO water suspensions.
TL;DR: The potential eco-toxicity of nanosized titanium dioxide, silicon dioxide, and zinc oxide water suspensions was investigated using Gram-positive Bacillus subtilis and Gram-negative Escherichia coli as test organisms, with antibacterial activity increasing with particle concentration.

Bactericidal activity of photocatalytic TiO(2) reaction: toward an understanding of its killing mechanism.
Pin-Ching Maness,Sharon Smolinski,Daniel M. Blake,Zheng Huang,Edward J. Wolfrum,William A. Jacoby +5 more
TL;DR: It is concluded that TiO2 photocatalysis promoted peroxidation of the polyunsaturated phospholipid component of the lipid membrane initially and induced major disorder in the E. coli cell membrane.

Investigation into the antibacterial behaviour of suspensions of ZnO nanoparticles (ZnO nanofluids)
TL;DR: In this article, the antibacterial behavior of suspensions of zinc oxide nanoparticles (ZnO nanofluids) against E. coli has been investigated and the effects of particle size, concentration and the use of dispersants on the behavior of ZnO nanoparticles were examined.
