Introduction: I believe that when it comes to nano-robots, everyone’s first reaction is that in the Hollywood blockbuster "Iron Man 3" that was seen on the screen that year, the reverse characters wanted to use nano-robots to spread the virus, so as to control humans. purpose.

In 1959, Professor Richard Feynman, an American physicist and Nobel laureate, felt that in the future, an ultra-micro-machine with a size similar to that of a molecule could be developed. Anything, therefore presents the concept of nanobots.
Nano-scale technology is no longer far away
At present, nano-robot has become one of the hot-spot technologies of high-tech, and has been invested in strategic high places by many countries. Many industry researchers say that the most important and urgent thing at present is to apply nano-robots in the medical field.
Someone asked, what is the role of medical nano-robots?
Medical nano-robots can be injected into human blood vessels for vascular care, health checks, precise administration, disease treatment, and organ repair, in addition to removing harmful DNA from genes. The body returned to normal. Some insiders have predicted that in the future, such intractable diseases such as cancer, AIDS, and high blood pressure will be solved. This also shows that nano-robots are the gospel of the medical field.
Development of medical nano-robots has been frequently obtained
In June 2013, scientists at Tohoku University in Japan published a research report that indicated that it has successfully developed a nanometer that can destroy cancer cells. robot.
A research report in August 2017 showed that scientists at Durham University, Rice University of the United States and North Carolina State University developed a method that can be drilled in minutes by means of light activation. Nano-robots that kill cancer cells and kill them.
In January 2018, scientists at the Technical University of Munich, Germany, said that electric field drive has been applied to nano-robots, which are used in medical diagnostics and drug development.
Medical NanomachinePeople are still in the research and development phase and have not been clinically practical on a large scale. But it is worth noting that nano-robots will bring about earth-shaking changes in biomedicine in the near future.
1, nano-robots are used as tumor treatments
Recently, a research report on how nano-robots treat tumors was published on Nature Biotechnology. According to foreign media reports, this research has given DNA nano-robots a powerful living transport and response recognition capability, and can intelligently combine multiple drugs to achieve efficient delivery, thereby promoting the development of new anti-cancer drugs. It has a very broad application prospect in nanomedicine.
2, nano-robots can be drilled into the eye to transport drugs
Recently, in the "Scientific Progress" magazine published the results of intentional research, the result of this research is Stuttgart's Max Planck intelligent system Researchers at the Institute's "Micro, Nano, and Molecular Systems" lab work together with a team of international scientists to develop a propeller-like nanorobot that can be drilled into the eye.
This nano-robot is a special coated nano-sized "transport" that can be active in a vitreous body with a dense tissue similar to the eye. It should be noted that before the results of this research were published, the transport of nanocarriers was only verified in model systems or biological fluids, and has not been successful in such dense tissues as humans.
