One of the challenges in the field of nanotechnology is environmental health and safety (EHS), including consideration of the properties of engineered nanomaterials (ENMs) that could pose dangers to the environment. Progress in the field of nanomaterial development and nanotoxicology was presented at the International Conference on the Environmental Implications of Nanotechnology at the Califor...

The interaction between engineered nanoparticles and the bacterial lipopolysaccharide, or endotoxin, is an event that warrants attention. Endotoxin one of most potent stimulators inflammation immune reactions in human beings, a very common contaminant research labs. In nanotoxicology nanomedicine, presence endotoxin on nanoparticle surface affects their biological properties leading to misinter...

Nanomaterials have the promise of revolutionizing current treatment and diagnosis of diseases, which has led to 33 nanotherapeutics drugs currently on the market and many more in various stages of clinical trials. With an increasing number of products available and in development, along with the unique, emergent properties of the nanoparticle therapeutics themselves, regulatory agencies are now...

The length scale for nanomaterial is small enough to be invisible and presume innocence for the initial avoidance of the toxicity issues. Again it was beyond the understanding of the time frame when nanotechnology just blooms that a length scale itself might be an important toxic parameter apart from its materialistic properties. We present this report to address the fundamental issues and ques...

In nanotoxicology, the capacity of nanoparticles of the same composition but different shape to induce cytotoxicity and genotoxicity is largely unknown. A series of cytotoxic and genotoxic responses following in vitro exposure to differently shaped CuO nanoparticles (CuO NPs, mass concentrations from 0.1 to 100 μg/ml) were assessed in murine macrophages RAW 264.7 and in peripheral whole blood f...
