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.

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.

Growth of Zinc Oxide Nanoparticles by the Reaction of Zinc with Ethanol
Advanced Materials Research, 2009A novel approach has been described for the synthesis of zinc oxide nanoparticles by a very simple reaction of zinc metal with ethanol at 100oC. The diameters of the nano-particles range from 50–100nm. The reaction involves the cleavage of C-O bond of the alcohol, which occurs readily on zinc metal surface.

Interaction of Zinc Oxide Nanoparticles with Soil Colloidal Suspensions
ChemosphereThe properties of soil colloids determine the interaction with nanoparticles, their behavior, and destiny in the soil environment including soil solutions. This study examines how several properties of soil colloids, including pH, phosphorus content, clay minerals, and iron oxyhydroxides, influence the interaction with zinc oxide nanoparticles (ZnO-nps)
