Encapsulation of Zinc Oxide Nanorods and Nanoparticles

Langmuir, 2009
A simple method for encapsulating zinc oxide nanoparticles within an organic matrix is described that consists of dispersing them in an ethanolic solution, adding an organothiol, and stirring while heating. Electron microscopy, photoemission, Raman spectroscopy, and thermal gravimetric analyses demonstrate that partial dissolution of the oxide occurs ...

Hepatocyte Cytotoxicity Evaluation with Zinc Oxide Nanoparticles

Journal of Biomedical Nanotechnology, 2013
Our 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.

Zinc Oxide Nanoparticle Removal From Wounded Human Skin

Nanomedicine, 2013
Nanoparticle removal from skin is relevant given the concern over topical nanoparticle toxicity. Zinc oxide nanoparticles (ZnO-NPs) are commonly used in sunscreens and their use is currently debated. This study explores the penetration and removal of ZnO-NPs from injured skin.Ex vivo/in vivo human skin was tape-stripped and/or microneedled followed by ...

ZINC OXIDE NANOPARTICLES FOR ULTRAVIOLET PHOTODETECTION

Frontiers in Electronics, 2011
Zinc Oxide ( ZnO ) nanoparticles were created by a top-down wet-chemistry synthesis process ( ZnO - A ) and then coated with polyvinyl-alcohol (PVA) ( ZnO - U ). In ZnO - U , strong UV emission was apparent while the parasitic green emission, which normally appears in ZnO suspensions, was suppressed.

Molecular mechanisms of zinc oxide nanoparticles neurotoxicity

Chemico-Biological Interactions
Zinc oxide nanoparticles (ZnONPs) are widely used in industry and biomedicine. A growing body of evidence demonstrates that ZnONPs exposure may possess toxic effects to a variety of tissues, including brain. Therefore, the objective of the present review was to summarize existing evidence on neurotoxic effects of ZnONPs and discuss the underlying ...
