rubescens. The two media have different zinc concentration, which explain the difference in the toxic effect of ZnO NPs and the Zn ions on microalgae11. The above studies have substantially increased our knowledge of the toxic effects of metal oxides NPs, based on short-term toxicity tests. ...
ZnO is inorganic crystalline metal oxide4. The unique properties ZnO NPs make them suitable for a variety of applications, including; biological5, opto-electronics6, medicinal7, energy storage8, and electrochemical applications. Until now, ZnO NPs could be synthesized via several methods, including;...
Discussion Multiple products containing ZnO NPs are used exten sively and thus may become easily ingested by children. Previous studies have explored the toxicity of ZnO NPs in the liver, ovaries, and testes of rats,6,18 but limited research has been conducted to explore their effects on ...
In the current study, CI-based platforms are prepared and sonochemically coated with ZnO or MgF2 nanoparticles (NPs), two agents previously shown to possess antibacterial properties. Additionally, a method is developed for coating both ZnO and MgF2 on the same platform to achieve synergistic ...
44 To solve this problem, we employed catechol as the anchoring group in this study to connect fullerene to the ZnO NPs since the bidentate ligands can passivate the under-coordinated Zn surface sites, resulting in tight binding of catechol to zinc oxide.45 Considering the steric hindrance of ...
non-metal. Enhancement of the activity of ZnONPs was reported in recent studies via combination with other metals [20,21], therefore doping of ZnONPs with Cu as a transition metal has showed a significant effect on the physical properties. Antibacterial activity of ZnONPs againstEscherichia coli...
However, studies have also indicated that ZnO NPs and Zn2+ toxicity are significantly different [29, 30]. Although ZnO NPs show a more substantial inhibitory effect on plant growth at a lower dosage than Zn2+, ZnO NPs restore more rapid plant growth than Zn2+ [30]. Moreover, studies ...
Our results support the hypothesis that the mechanism of ZnONPs cytotoxicity is based on the release of free zinc ions. Nevertheless, both previously quoted hypotheses incompletely described the mechanism of action of ZnONPs. In this paper, we show that the mechanism of cytotoxicity of ZnONPs is...
ZnO is known to be less toxic than metallic NPs and hence it is expected that formation of oxide layer will decrease the toxicity of silver. Additionally, earlier studies by He et al. and Gondal et al. have shown significant antifungal behavior of ZnO against Botrytis cinerea, Penicillium ...
However, TiO2and ZnO nanoparticles (NPs) are most widely used photocatalysts owing to their excellent photocatalytic performance, high chemical stability, and non-toxic nature. The degradation efficiency also depends upon the morphology of the materials or catalyst, like the spherically shaped Zinc ...
