U.S. scientists develop nano-robots that can be injected into the human body
Western media said that researchers at the University of Pennsylvania and Cornell University used the latest nanotechnology to create an army of millions of nanobots within a few weeks. According to the Spanish "Abesai" website reported on March 10, this design is based on a nano-manufacturing technology that can turn a silicon wafer about 10 cm long into millions of robots in a few weeks. Each nano-robot is about 70 microns long (about the thickness of human hair), and the body of the robot is composed of an ultra-thin rectangular skeleton. The top of the robot is covered with a thin layer of silicon, and the researchers installed "tissues" such as the "brain" of the robot: electronic control elements and miniature solar cells. Their legs are made of a double-layer structure of platinum and titanium or graphene, and their width is only equivalent to 100 atoms. It is reported that these nanorobots have several incredible functions: they can receive energy without any wires, can walk and can survive in harsh environmental conditions. In addition, they are tiny enough to enter the body through subcutaneous injection. How can such a small robot do all this? According to the report, the trick is that the researchers fired laser light on the robot's solar cell to power it, and then platinum would expand while titanium remained rigid, causing the legs to contract. Solar cells cause the front and back legs to alternately contract or relax, so the robot will have a walking gait. According to the report, at present, the main obstacle to this research is to find a new energy source, because any fabric thicker than the nails will make it impossible to control the robot through the laser. The researchers plan to study how to drive these robots with magnetic fields and ultrasound, so that they can work inside the human body, such as delivering drugs on demand.
