Image Description:  

Vanishingly small machines like the ones envisioned here could someday serve as tiny mechanical doctors. These miniature devices would roam between the red cells of the bloodstream, seeking out and destroying harmful viruses (shown here as green geometric solids). The working parts of these machines would be built around gears no bigger than a protein molecule.
