Molecular machine takes control

Abstract:
For years, nanotechnology has held out the hope of molecular-scale contraptions that can manufacture custom-made drugs or revolutionize the way computer chips work.

Now researchers in Japan say they have taken a big step toward that nano goal by creating the first molecular machine that can do parallel processing.

"The discovery could provide a way to control many molecular machines simultaneously, increase computer processing power, and perhaps keep Moore's Law alive," according to the Proceedings of the National Academy of Sciences, which published the researchers' paper online today.

The multitasking machine was coaxed to assemble itself on a surface of gold from 17 molecules of an organic compound called duroquinone. Sixteen of the molecules form a weakly bonded ring around the central molecule, which serves as the control unit for the machine.
