A molecular motor in a liquid-crystal film uses light to turn items thousands of times larger than itself.

Nanomachines of the future will require molecular-scale motors1, 2, 3, 4, 5, 6 that can perform work and collectively induce controlled motion of much larger objects. We have designed a synthetic, light-driven molecular motor that is embedded in a liquid-crystal film and can rotate objects placed on the film that exceed the size of the motor molecule by a factor of 10,000. The changes in shape of the motor during the rotary steps cause a remarkable rotational reorganization of the liquid-crystal film and its surface relief, which ultimately causes the rotation of submillimetre-sized particles on the film.
