Nanotechnology risks – where are we today?

September 14, 2007

New technology, whether it is a novel cancer treatment or an innovative approach to making a new material, almost always comes with risk. Nanotechnologies are no different. Certain nano-fabrication techniques employ toxic chemicals, the production of carbon nanotubes results in dangerous byproducts, and the big question as to what degree certain engineered nanoparticles could be harmful to humans and the environment has not been answered yet.
