Chiral fuel drives molecular machine’s rotation, mimicking fundamental biological processes

A new molecular motor consumes chiral fuel to drive rotation in one direction around a single covalent bond. The 26-atom machine is powered by a catalytic reaction and mimics aspects of biological processes.
