Nano Spider, Robot Destroyer Cancer of the Body

COLOMBIA - Scientists have created a microscopic robot from DNA molecules can walk, turn and even create products in their own little nano-scale assembly line.

Revolutionary device that is described in the journal Nature this in the future is expected to lead the army surgeon robot that cleans human arteries or build computer components inside.

Reported the Daily Mail, one of the proponents of this project from New York's Columbia University has even developed a spider robot measuring 4 nanometers or about 100,000 times smaller than the diameter of a human hair.

Robot spiders are expected to walk along the path of DNA. By using the path in the order, the robot can be made to walk, turn left or right according groove of DNA strands.

Robot body is made up of a protein called streptavidin. Attached to a three-legged 'enzymatic' DNA single strand binding and fourth legs are strands that bring the spider to the starting point.

"After the robot is released from the trigger, it will bind and then cutting the DNA strands," says Milan Stojanovic, chairman of the project team. After the thread is cut, robot legs began grabbing lines and DNA matching. with this, the robot is guided into the path set by the researchers.

To view the robot is moving, the researchers used an atomic force microscope. Amazingly, this robot can record signs of the disease on the cell surface, the cell determines it is cancer, destroying cancer cells even robots that can deliver compounds to kill him.

Apparently 'DNA walk' has been developed in the past, but they never achieve such a feat today. "The robot can run up to 100 nanometers, or about 50 steps," said Professor Yan from Arizona State University.

"This is the first time the system is used nanomachines to perform the operation. An important advance in the evolution of DNA technology," said Lloyd Smith of the University of Wisconsin, Madison. Nearly 6 billion pounds invested in the research and development of nano products worldwide.
