in recent years, it has become evident that it is necessary to systematically and accurately define particle characteristics in order to understand the potential toxicity of nanoparticles to biological systems. the properties that need to be emphasized are size, shape, dispersion, doping, aggregation, functionalization, physical and chemical properties, surface area, and surface chemistry. rout...

In a recent paper published in Toxicological Sciences, "Inhalation Toxicity of Multi-wall Carbon Nanotubes in Rats Exposed for Three Months", a team of European researchers have reported the findings of a 90-day inhalation toxicity study of multi-walled carbon nanotubes (MWCNTs) in rats. This study led by Robert Landsiedel, Head of the Short Term Toxicology Department at BASF SE in Germany not ...

Enclosed-space smoke inhalation is the fifth most common cause of all unintentional injury deaths in the United States. Increasingly, cyanide has been recognized as a significant toxicant in many cases of smoke inhalation. However, it cannot be emergently verified. Failure to recognize the possibility of cyanide toxicity may result in inadequate treatment. Findings suggestive cyanide toxicity i...

Objective(s): Nanomaterials, especially silver Nanoparticles (Ag-NPs), are employed in an increasing number of commercial products. This has led to an ever growing exposure of human beings to this substance. The first purpose of the Nano Committee of Food and Drug Administration of The Islamic Republic of Iran (IFDA) is developing guidelines to assess and approve commerci...
