Robots in size of molecules

Molecules that behave like robots created

In a significant advancement in the nascent fields of molecular computing and robotics, researchers in the US have created and programmed robots the size of a single molecule that can move independently across a nano-scale track. Scientists are hoping the achievement could someday lead to molecular robots that can fix individual cells or assemble nanotechnology products, reports Zee news.

Researchers have created and programmed robots the size of single molecule that can move independently across a nano-scale track.

The development, by Researchers from Columbia University, Arizona State University, the University of Michigan and the California Institute of Technology (Caltech), marks an important advancement in the nascent fields of molecular computing and robotics.

Recent molecular robotics work has produced so-called DNA walkers, or strings of reprogrammed DNA with ”legs” that enabled them to briefly walk.

Now the researchers has shown these molecular robotic spiders can in fact move autonomously through a specially-created, two-dimensional landscape.

The spiders acted in rudimentary robotic ways, showing they are capable of starting motion, walking for awhile, turning, and stopping.

In addition to be incredibly small–about 4 nanometers in diameter–the walkers are also move slowly, covering 100 nanometers in times ranging 30 minutes to a full hour by taking approximately 100 steps.

While the field of molecular robotics is still emerging, it is possible that these tiny creations may someday have important medical applications.

May be in Future, “G I Joe” will become true…
