Nanotech looms large for meds

Wired: “Researchers have designed nano-scale tools so small they can chew up or explode bio-warfare agents on the molecular level, or
make a single molecule glow so brightly that you can see it with only the help of a microscope.

How small can it go? Ten to the negative 9th meter. To compare, the sun is 10 to the 10th meter away from earth.”
