Amazing stuff.
Nano technology for internal medicine is one step closer to reality, one day they will be able to inject individuals with purposely designed little doctor type robots to attack diseases like cancer.
By modifying the molecule slightly, it could be used to generate microwave radiation or to couple into what are known as nano-electromechanical systems, Dr Sykes said.

Tiny rotors based on single molecules have been shown before, but this is the first that can be individually driven by an electric current.
"People have found before that they can make motors driven by light or by chemical reactions, but the issue there is that you're driving billions of them at a time - every single motor in your beaker," said Charles Sykes, a chemist at Tufts University in Massachusetts, US.
"The exciting thing about the electrical one is that we can excite and watch the motion of just one, and we can see how that thing's behaving in real time," he told BBC News.
