Pitt researcher developing tiny drone

The University of Pittsburgh is developing a a tiny drone that could swim through the human body.

Doctor Sung Kwon Cho has just received a nearly three-quarter of a million dollar grant from the National Science Foundation to work on the technology.

Besides more precise bio-imaging, the swimmer drone can also deliver a drug to a specific target, like a cancer or tumor.

The drone is about one millimeter and the width of a hair.
