University of Michigan researchers propose that tiny “nano thrusters” could be made into flat sheets mounted on the side of spacecraft.

Nanoparticles just tens of nanometers across are ionized by electrodes in a chamber. Those charged ions are accelerated by the electric field and ejected from a vent, producing thrust.
