Scientists at Columbia University in the United States have recently succeeded in developing a "nano-spider" micro- robot composed of DNA molecules that can walk, move, turn, and stop freely following the trajectory of DNA, and they can freely surface on two-dimensional objects. walk. It is reported that this "nano spider" robot is only 4 nanometers in size, which is smaller than one hundred thousandth of the diameter of human hair. The invention of the "Nano Spider" robot is an improvement and upgrade of the "Spider Molecule" robot a few years ago. Its function is more powerful. This nano robot can not only walk freely on the surface of two-dimensional objects, but also swallow bread crumbs. Chips. Although the previously developed DNA molecular robot also has a walking function, it does not exceed 3 steps, while the "nano spider" robot can walk a distance of 100 nanometers, which is equivalent to walking 50 steps. "Nano" robots can be used in medical applications to help humans identify and kill cancer cells for the purpose of treating cancer. They can also help people complete surgery, clean up arterial waste, and make up new computer hardware. Scientists have developed a production line for such robots.
