Think small—really small. Some nanotechnology devices are as small as one nanometer, or 1/80,000th the width of a human hair. At these sizes, it is no wonder that scientists have seized upon nanotechnology for its potential in medical applications. In the not-too-distant future, as this slide show reveals, dozens of nanodevices may transform cancer diagnosis, treatment, and prevention.

Structures smaller than a single red blood cell could revolutionize cancer diagnosis and treatment.
