Scientists Look to Sperm to Power Nanobots

"According to MSNBC, scientists are experimenting with using a sperm's flagellum to overcome the problem of supplying energy to nanobots that could be implanted in the body as smart probes that would release disease-fighting drugs, monitor enzymes and perform other medical roles within a patient's body. Powered by a compound called adenosine triphosphate or ATP, a sperm's flagellum can propel it at about 7 inches an hour. Energy from ATP could also power the pumps charged with dispensing the medication at a certain rate from the nanobots."
