Experimental and modeling study of ZnO:Ni nanoparticles for near-infrared light emitting diodes.

This work is devoted to the synthesis and study of the different properties of ZnO nanoparticles (NPs) doped with the Ni element. We have used a simple co-precipitation technique for the synthesis of our samples and various structural, morphological and optical techniques for their analysis. Energy-Dispersive X-ray spectroscopy (EDX) confirms the stoichiometry of the samples.

In deep evaluation of the neurotoxicity of orally administered TiO nanoparticles.

Titanium dioxide nanoparticles were widely used in food as dietary supplements, in drugs, in toothpaste, ect. Few numbers of studies were interested to the neurotoxicity of TiO NPs through oral pathway. The present study aims firstly to understand the connection between the physicochemical properties of TiO NPs and their associated toxicological oral pathway by evaluation the colloidal stability of TiO NPs over time in different media simulating physiological gastric, intestinal and serum conditions at 37 °C to be close to the oral administraton.

The effect of titanium dioxide nanoparticles on neuroinflammation response in rat brain.

Titanium dioxide nanoparticles (TiO NPs) are widely used for their whiteness and opacity in several applications such as food colorants, drug additives, biomedical ceramic, and implanted biomaterials. Research on the neurobiological response to orally administered TiO NPs is still limited. In our study, we investigate the effects of anatase TiO NPs on the brain of Wistar rats after oral intake.

Anemia and genotoxicity induced by sub-chronic intragastric treatment of rats with titanium dioxide nanoparticles.

Titanium dioxide nanoparticles (TiO2 NPs) are widely used for their whiteness and opacity. We investigated the hematological effects and genotoxicity of anatase TiO2 NPs following sub-chronic oral gavage treatment. TiO2-NPs were characterized by X-ray diffractometry (XRD), X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM).
