A microscopic robot has been taught to sort DNA molecules

Nanobots capable of working inside the human body, are extremely promising development. They make a diagnosis, to monitor people's health and even cure diseases. But something new in this area invented by scientists from the California Institute of technology. They have developed tiny bio-robot which can "walk" on the surface of the DNA molecule and even to rebuild the chain.

The robot scientists collected from three main elements: the body, «limbs» for movement and the capture molecules and the part that is responsible for orientation in space and «communication» with the external environment. As reported by the developers in an interview with the journal Science,

«Similar to how mechanical robots working in our world, our molecular robots designed for missions within the body. For example, in the bloodstream. Our goal was to develop and establish a molecular robot that could perform complex nanomechanical task: sorting DNA molecules».

The Robot with «limbs» moves along the DNA strands. It «travel» continues until until it gets to the molecules that it needs to move. In 5 minutes, the robot moves a distance of 6 nm. During a series of experiments to test new technologies biorobot sorted six fluorescent molecules of different colors in 24 hours, moving on «track» from the DNA of an area of 58 square nanometers. Now scientists are busy optimizing the robot motion. According to experts, the principles of the bio-robot can be used for the synthesis of drugs directly inside the human body.
