>> In here we have some molecular machines.>> The world's smallest machines. A trio of scientists awarded the Nobel prize for chemistry on Wednesday for their work on molecular motors. France's Jean-Pierre Sauvage, Scottish scientist J Fraser Stoddart and Dutch scientist Bernard Feringa developed molecules with controllable movements that can perform tasks in response to a stimulus.
And they're miniscule. Some are a thousand times thinner than a human hair, but Reuters science correspondent, Ben Hirschler, says their impact could be very large indeed.>> No one's yet got a killer application for them. But they've got potential in medicine and energy storage. So you could envisage that perhaps you'd inject one of these into a patient.
Then it can go and find a cancer and deliver a drug. Or maybe it might be used to deliver or to make new energy storage systems for the future. So it's a bit like the first electric motors which were invented in the 1830s, or the first flying machines.
No one quite knew then that would lead to washing machines and jumbo jets. So we don't quite know where this is going but it's an exciting area.>> Stoddart, a chemistry professor at Northwestern University in the United States was surprised and elated to learn of the three way win.
Chemistry is the third and last of the Nobel science prizes to be awarded this week after physics and medicine.
