Einstein said: "The science of the future is nothing more than continuing to march into the macro world and the micro world." In the science and technology that shocked the world, the field of nano-robots must be a true epic-level technological innovation - human beings are building a molecular size Micromachines, which use molecules or even individual atoms as parts to build matter in very small spaces, means that humans can make any changes to the atom and cell structure!
In 1959, Nobel laureate and theoretical physicist Richard Feynman pioneered the idea of ​​nanotechnology. He presented in a speech entitled "There is a lot of space at the bottom of matter": "Human will Level micro robots are used for medical treatment ."
With the development of technology, Richard Feynman's idea is gradually being realized: combining millions of micro-mechanics into one, and recording the procedures and operational processes into nano-robots, they can move freely in the human body. Just like the fantasy in science fiction: With nano-robots, cancer will be cured, human life will last for hundreds of years, and all degenerative diseases will cease to exist. The wound will heal in seconds, some drugs will no longer have side effects, and the feeling of hangover discomfort will not exist - nanobots can "cure the whole world."
Today's robots have become a hot topic in the scientific community. With the rise of nanotechnology in the 1990s, research on micro-robots has blossomed around the world, especially in the application of nano-robots in biomedicine. The 21st century is an era of life sciences. The combination of nanotechnology and biomedicine will be an important part of life sciences in the 21st century, and nanobots will be the most tempting achievements in nanobiology.

In fact, the cutting-edge technology of nano-robot is still in the experimental development stage, and how does a robot with a size of one hundred thousandth of a hair swim in the blood? The current technology is that nano-robots rely on tiny capacitors to power the tail (or limbs), have payloads in their bodies, and have a miniature camera on the head for finding targets.
There is also a nano-robot that uses a nano-engine to walk, place synthetic nano motors in living human cells, and control them by ultrasound. Nano-engines have little effect on cells at low ultrasound power, but after increasing power, they move within the cell, striking the cell structure, reconciling the contents of the cell, and even piercing the cell wall. Nanoengines can also treat cancer by performing mechanical manipulation of cells from within, performing intracellular surgery, or delivering drugs directly to living tissue.
Any use of nanotechnology in the medical field will lead to a medical revolution that can even change human life. Since 1981, G. Binnig and H. After Rohrer invented the Scanning Tunneling Microscope in the laboratory of IBM Zurich, human research on nanobots has never been interrupted. The development of nano-robot belongs to the category of molecular bionics. It is designed and manufactured according to the biological principle of molecular level, and is controlled and operated in nano-space.
Possible medical applications for nanobots include: treatment of arteriosclerosis, clearing of blood vessel embolism, removal of fat deposits in arteries, precise killing of cancer cells, treatment of body masses, removal of parasites, treatment of gout, kidney draining and cleaning of wounds. When you have a cold, the doctor does not need to give you an injection, but instead implants a nano-robot in the blood. This robot detects the source of the cold virus in the body and reaches the virus where it directly releases the drug to kill the virus.
　 Nano-robots that are beginning to see technology
1. Clottocyte nanorobot that releases clots
The hemostasis process of the human body is more complicated. The whole process takes 2 minutes to 10 minutes. The first stage is the formation of a natural thrombus. It usually consists of three steps: platelet adhesion, platelet aggregation, plug formation and platelet release. The second stage is fiber deposition. Quickly form a random fiber network at the wound, catching platelets and other blood cells, and forming clots. Anti-clotting nanobots can function like platelets and stick together to form blood clots to stop bleeding. This nano-robot can store fibers, and when they encounter a wound, they quickly release the fibers to create a clot that takes much less time than platelet aggregation, which takes about one second.
