A review on Nano toxicology of metal oxide nanoparticles

Nanotechnology play a prominent role in our economy. Used of nanaomaterials increased poses potential human health risk. Therfore it is critical to understand nature and origin of the toxicity imposed by nanomaterial.This paper discusses synthesis, characterization and toxicity of metal oxide nanopartical. There are two toxicities are in victro and in vivo of its oxide. These oxide are discussed including a consideration of a factor important of safe use of these nanomaterials. In these article toxicity of metal oxide are widely use in industry and bio technology. Nanoparticle toxicity is related to the oxidative stress and alteration of calcium homeostasis cellular signally events. Nano technology is express to address the toxicological activities of nanoparticles and there products to determine whether and to human health ,and define as the study of the mechanism of the toxic effect of nanoparticles on living organism. The help of knowledge of nanotoxicological study will be the base for designing safe nano materials in different biological system. These paper consist of the section with the brief introduction ,the synthesis of metal oxide nonoparticle. Nonotoxicity of metal oxide of nanoparticle etc.
