Nano-fiction machine in 1867 became a reality

About 150 years ago, this machine was just an imaginary concept of a scientist, but now researchers have created a type of motor that can lead other creations of the nano machine.

Scottish physicist James Clerk Maxwell, who was the first to discuss atomic-sized devices in the 1867 Demon work. Scientists at the Edinburgh University (Scotland) turned it into reality.

' We had a new engine for nano machines ,' said Professor David Leigh of the Department of Chemistry.

Nanoscale machines are incredibly small devices with parts that include single molecules. Nature uses nanotechnology in everything, from photosynthesis to motor muscles in the body and transmitting information through cells.

Nano engines have been researched for many years by scientists, but now, when they have been made, we still don't know what the machine can do .

Scientists are trying to clarify the secrets of nanoscale machines and nanotechnology. A nanometer is 1 billionth of a meter, or less than 80,000 times the thickness of a human hair. ' Molecular devices that allow life to rise to a molecular-level sophistication by itself. Our new engines are a small step towards future molecular devices, 'Leigh said.

His machine can track the motion of molecular particles. Just as Maxwell predicted long ago, it didn't need energy because it worked with light. ' When light is first used to power the small parts directly, it will be the first time the system has shed light on tracking molecules as it moves in the correct direction under transport. Naturally, 'still follows Mr. Leigh.

Mr. Leigh noted Maxwell's recognition in building a foundation for understanding how light, temperature and molecules work. In previous studies, he and his research group exhibited a nanoscale machine that could move a drop of water using molecular force. Although the movements are slow, it is a big step in the study of making machines with artificial molecular technology.

The new machine helps scientists perform tasks close to the way natural biological machines still do the most.

Nanotechnology has been used in cosmetics, computer chips, sun screens, self-cleaning windows and heat-resistant clothing. Leigh believes that nanotechnology can have a big impact on society - in relation to the impact of electricity, steam and the Internet.

But how, it's hard to guess.
