Now on the molecular scale: Electric motors

Electric vehicles, powered by macroscopic electric motors, are increasingly prevalent on our streets and highways. Now a multidisciplinary team 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.
