A review: zinc oxide nanoparticles – friends or enemies?
International Journal of Environmental Health Research, 2020Modern nanotechnology allows obtaining zinc oxide nanomaterials with unique properties that let its use in a wide range of commercial applications. Direct contact with these particles as well as their release into the environment is almost inevitable. This review aims to consider whether the toxicity of zinc oxide nanoparticles found in numerous test ...

Interaction of cytochrome c with zinc oxide nanoparticles
Colloids and Surfaces B: Biointerfaces, 2013The influence of pH on the interaction between horse heart ferricytochrome c (cyt c) and zinc oxide nanoparticles (ZnO NPs) has been studied by a small angle scattering as well as UV-vis and FTIR spectroscopy. The observations showed that the optimal pH for the association of protein with nanoparticles is in pH range 5.0-8.0.

Hydrogen sensors based on zinc oxide nanoparticles
2010 IEEE 5th International Conference on Nano/Micro Engineered and Molecular Systems, 2010Pure ZnO, pure MgO and 5 wt%MgO/ZnO nanocomposites were produced by flame spray pyrolysis (FSP) in a single step using zinc naphthenate and magnesium acetate tetrahydrate as Zn and Mg precursors. The particle properties were analyzed by XRD, BET and TEM analyses. The sensing films were prepared by mixing the nanoparticles into an organic paste composed

Hepatocyte Cytotoxicity Evaluation with Zinc Oxide Nanoparticles
Journal of Biomedical Nanotechnology, 2013Our innate immunity is composed of several integral leukocytes including neutrophil, NK cell, macrophage or so. They are usually known to produce reactive oxygen species (ROS), in order to induce cell damages by these oxidizing reagents, and finally disrupting mitochondrial membrane to release cytochrome c.

The toxicology of ion-shedding zinc oxide nanoparticles
Critical Reviews in Toxicology, 2016Zinc oxide nanoparticles (ZnO NPs) are nanomaterials that are widely used in many fields. ZnO NPs are ion-shedding particles, and zinc ions produce important and potent effects that differ from those of other metal or metal oxide NPs. Several studies have reported the toxicological effects of ZnO NPs administered via several different routes, including

Acute Toxicity of Ferric Oxide and Zinc Oxide Nanoparticles in Rats
Journal of Nanoscience and Nanotechnology, 2010We investigated the toxic effects of inhalation exposure to ferric oxide (Fe2O3) and zinc oxide (ZnO) nanoparticles in rats. Male Wistar rats were consecutively treated with Fe22O3 at 8.5 mg/kg body weight and ZnO nanoparticles at 2.5 mg/kg body weight, twice daily for 3 days.
