Gallery: The World’s Smallest Train is Made from DNA


A recent breakthrough in DNA nanotechnology has brought to life the world’s smallest autonomously functioning DNA motor – a teeny tiny train of molecules that has been programmed to navigate a network of tracks with multiple switches. The discovery, which comes from researchers at Oxford University and Kyoto University, paves the way for the development of even more complex nanosystems,  including programmable molecular assembly lines and sophisticated sensors.
