Now a multidisciplinary team led by Northwestern University has made an electric motor you can't see with the naked eye: an electric motor on the molecular scale.

This early work -- a motor that can convert electrical energy into unidirectional motion at the molecular level -- has implications for materials science and particularly medicine, where the electric molecular motor could team up with biomolecular motors in the human body.
