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.
