Jean-Pierre Sauvage, Sir J. Fraser Stoddart and Bernard L. Feringa have been jointly awarded the Nobel Prize in Chemistry “for the design and synthesis of molecular machines.” In other words, this trio developed the world’s smallest machines by linking together molecules into a unit that, when energy is added, could do some kind of work. These machines, a thousand times thinner than a strand of hair, included a tiny lift, mini motors and artificial muscles.
