Researchers Size Up Nanotechnology Risks

JAMA. 2005;294(15):1881-1883. doi:10.1001/jama.294.15.1881

Nanotechnology, a burgeoning field featuring tiny materials, may be poised to transform medicine with potential uses spanning all aspects of disease diagnosis, prevention, and treatment. In oncology alone, researchers envision using nanomaterials (which by definition have at least one dimension ranging from 1 nm [one billionth of a meter] to 100 times that) to detect early cancers, pinpoint tumors within the body, deliver toxic drugs specifically to malignant cells, and determine a therapy’s effectiveness. Similar medical uses may exist for arthritis, heart disease, and many other conditions.
