Blood-swimming drugbots

blood cells

Tiny robots. In your blood. That dispense drugs. At least that's what scientists at the Chinese Academy of Science and the University of Science and Technology of China are promising if they can get the 3 millimeter-long drugbot they've built, which is still pretty big for something that's going to be passing through your blood vessels, down to a tenth of a millimeter. Then it's party time, er, healthy time.
