Nanotechnology may hold risks, scientists warn

New types of materials and chemicals that are invisibly small -- i.e., with diameters measured in nanometers, or billionths of a meter -- have many possible valuable uses in medicine, environmental cleanups, water treatment, energy production, technology and other areas, representatives of the Washington-based group Environmental Defense acknowledged at a news conference Wednesday. However, uncertainties linger over the possible harm of nanomaterials and nanoparticles on human health and the environment, they cautioned.
