Scientists have created microscopic robots from DNA molecules can walk, turn and even create products of their own small nanoscale assembly line. This revolutionary device described in the future is expected to lead the troops robot surgeon could clean human arteries or build computer components inside.
Have developed a spider robot measuring 4 nanometers or about 100,000 times smaller than the diameter of a human hair. Spider robot is expected to walk along the path of DNA. By using the groove in accordance with the order, the robot can be made to walk, turn left or right according groove of DNA strands. This robot body composed of a protein commonly called streptavidin. Three legs attached to it ‘enzymatic DNA’ single-strand binding and the fourth leg is a string that carries the spider to the starting point.
After the robot is released from the trigger, it will bind to and then cutting the DNA strands. After the thread is cut, the robotic legs began to gain track and match DNA. With this, the robot is guided into the path set by the researchers. To view this robot moves, the researchers used an atomic force microscope. This robot can record signs of disease on the cell surface, determining the cell is a cancer, destroying cancer cells even robots that can deliver compounds to kill him. Read more
