There is currently a large difference of opinion in nanotoxicology studies of nanomaterials. There is concern about why some studies have indicated that there is strong toxicity, while others have not. In this study, the length of carbon nanotubes greatly affected their toxicity in zebrafish embryos. Multiwalled carbon nanotubes (MWCNTs) were sonicated in a nitric acid solution for 24 hours and...

The term hormesis describes a dose-response relationship that is characterized by a response that is opposite above and below the toxicological or pharmacological threshold. Previous reports have shown that this relationship is ubiquitous in the response of pharmaceuticals, metals, organic chemicals, radiation, and physical stressor agents. Recent reports have also indicated that certain nanopa...

In this review we hope to explain regarding nanoparticles (NPs), Nanoparticles are very small materials that range from 1 100 nm size. And the subclasses of mentioned. Nanomaterials formulated by nanoparticles. Research on nanomaterials is used improve in material technology and synthesis gained support. gradually becoming popularized starting arise as commodities. Nanotechnology refers a set s...

although the applications of nanotechnology have been widely studied, the risk measurement and assessment of nanoparticles effect on biological systems and ecosystems has not been clearly demonstrated. the small size and specific properties of nanoparticles makes them a carrier for toxic chemical pollutants. several studies show the nanoparticles and nanotubes can release in the environment and...

Engineered nanomaterials (ENMs) are a diverse class of materials whose distinct properties make them desirable in multitude applications. The proliferation nanotoxicology research has improved our understanding ENM toxicity, but an under appreciation for their potential to interfere with biochemical assays hampered progress the field. physicochemical ENMs can promote interaction membranes or bi...

Although researchers have intentionally produced and used nanomaterials for more than a century, nanotechnology has made its mark in most areas of daily life in the past 20 years. Now thousands of products contain nanoparticles, nanofibers, or nanostructured parts. Because some chemical products have caused severe problems to human health and to the environment, we should consider the overall b...

The rapid rise of nanotechnology has resulted in a parallel the number products containing nanomaterials. unusual properties that nano forms materials exhibit relative to bulk driven intense research interest and relatively adoption by industry. Regulatory agencies are charged with protecting workers, public, environment from any adverse effects nanomaterials may also arise because these novel ...
