1867 nanomachine now reality

Breaking News

Nearly 150 years ago it was no more than a concept by a visionary scientist, but researchers have now created a minuscule motor that could lead to the creation of microscopic nanomachines.

Scottish physicist James Clerk Maxwell first imagined an atom-size device dubbed Maxwell's Demon in 1867. Scientists at the University of Edinburgh have made it a reality.

"We have a new motor mechanism for a nanomachine," said David Leigh, a professor of chemistry at the University.

A nanomachine is an incredibly tiny device whose parts consist of single molecules. Nature uses nanomachines for everything from photosynthesis to moving muscles in the body and transferring information through cells.
