Scientists have created the world's smallest electric motor. Electric motor is made of one millionth of a meter-sized molecules. The work of these scientists published in the journal Nature Nanotechnology, Monday (04/09/2011). The smallest electric motor can later be instrumental in the medical world and nantoteknologi.

Electric motors of one molecule ever made before, but this time the electric motor is the first that can be driven electricity. "People have been making a motor that can be driven light and chemical reactions. But there, you move millions at the same time," said Charles Sykes, an expert in chemistry from Tufts University in Massachusetts.

"The surprise of the electric motor is, we can see the movement of a molecular motor, to see how the behavior of small motors," added Sykes was quoted as saying by the BBC, Tuesday (05/09/2011).

Sykes could control the nanoscale with the electric motor through the aid of low temperature scanning tunneling microscope (LT-STM). The tool uses electrons to see the molecule. Sykes uses the microscope tip to supply power to the butyl methyl sulfide molecules that have been placed on the surface of the conductive copper. Due to the supply of electricity, nanoscale motor was spinning.

LT-STM can also be used to see the motor spinning. Known motor can spin both ways and moves with the speed of 120 revolutions per second. The ability of this motor motion could be modified. Through the process of modification, for example, scientists could create microwave radiation arau create nano-electromechanical systems.

Electric motors can also be useful in the medical world, to ensure targeted drug delivery. To get there still need some langkah.Saat these new researchers will
