In this interactive slideshow adapted from NOVA scienceNOW, learn how scientists are using nanotechnology—the building of functional systems at the molecular scale—for medical purposes. Through a mix of electron microscope images, artistic representations, and informative text, examine a variety of nanotechnology applications that have been conceived to diagnose, treat, and even prevent cancer. The slideshow features nanotubes, nanowires, quantum dots, and fullerenes, among several other extremely small devices and particles currently in research and development.
