A few days ago, American futurists issued a shocking prediction that humans will begin to achieve eternal life more than a decade later. The nanotechnology mentioned is particularly eye-catching – in the future, not only can nano-robots take over the immune system, these hidden Micro-robots in the blood can even reverse the aging process. In 2029, can humans really achieve eternal life with the help of nanotechnology?

Man will achieve eternal life in 2029
In this era of ever-changing science and technology, we can always hear from the mouth of the "scientific madman" about the "prophecy" of the future of mankind. For example, not long ago, Google chief futurist Ray Kuzwell said in an interview that humanity will begin to achieve eternal life in 2029.
Bill Gates once commented on him - Ray is the person who knows the best in predicting artificial intelligence. Because Ray Kuzwell’s “prophecy†is based on the development of biotechnology, it seems that it is not so unrealistic. Ray Kuzwell claims that biotechnology is revolutionizing clinical medicine, and that it will revolutionize medicine in the next decade or two. Among the high-tech technologies he mentioned, the most striking thing is that scientists are beginning to reinvent the outdated “life softwareâ€, which is called 23,000 “small programs†in the human body. By reprogramming, they will help people stay away from disease and aging. By 2020, nano-robots will be used to take over the immune system; by 2030, nano-robots in the blood will be able to destroy pathogens, remove debris, blood clots and tumors, correct DNA errors, and even reverse the aging process.
"Our immune system is very picky, leading us to a variety of diseases such as allergies, autoimmune diseases and even cancer." Kuzwell said, "For example, the immune system has little effect on cancer. It thinks cancer is human." Normal cells in the body, so do not treat cancer as an enemy. Similarly, it does not work for retroviruses. The immune system does not help much in our future life, because it is not evolved to achieve longevity." He believes that the future of nano-robots will replace T cells - a blood cell associated with our immune system; if the cells can attack cancer cells, then there is a chance to alleviate the disease.

Nano robots enter the human body to eliminate viruses
I don't know if you still remember that in the movie "Amazing Adventures", scientists injected tiny people and spaceships into the human body, allowing these reduced "visitors" to directly view the organization and operation of various organs of the human body. That's right, this is the earliest human speculation about nanobots.
When we mention "nano", we will immediately think of "very small." "Nano" is a unit of measure of length, also known as nanometer; to be professional, 1 nanometer is equivalent to 4 times the atomic size, which is smaller than the length of a single bacteria. The term "nanotechnology" has been in existence for a long time. This science and technology, which uses single atoms and molecules to make matter, based on many modern advanced science and technology, will lead to a series of new science and technology in the future - nanophysics, Nanobiology, nanochemistry, nanoelectronics, nanofabrication technology and nanometer metrology. Nano-robots are undoubtedly the most tempting content in nanobiology.
"Nanobot" is an emerging technology in robotics engineering. This concept was proposed by Nobel Prize winner Richard Feynman. He believes that in the future, human beings may build a molecular-sized micromachine that can Molecules and even individual atoms act as building blocks to build matter in very small spaces. Broadly speaking, systems that can move and operate at the nanoscale can be called nanobots. Perhaps it won't take long for a nano-molecular robot with a molecular size to continue into the daily life of human beings, and it will be a future human body doctor. When you have a cold and fever, you don't need to go to the hospital to take medicine and take it instead. You implant nanobots in your blood, let them detect the source of the virus in the body, and "destroy" it wherever the virus is.

By programming, nano-robots can kill cancer cells
Because of the mini-body type, the extreme environment is the most important stage for nano-robots to display their talents. They can make a big difference in the fixed-point drug delivery and targeted therapy in the precise organization of the human body. In 2010, American scientists developed a nano-spider robot made of DNA. These "doctors", which are only 4 nanometers long and one hundred thousandth smaller than the diameter of human hair, can be activated according to the trajectory of DNA. Features such as movement, steering, and stop, scientists can program to identify cancer cells and control nano-spiders to kill cancer cells.
Let micro-robots fight disease in our blood, which sounds like science fiction. According to Kuzwell, the future nano-robots will replace T cells. If T cells can attack cancer cells, there is a chance to alleviate the disease. He hopes to replace the human T cells with nano-robots to further improve this therapy. So the question is, what exactly is the "T cell" and what role does it play in our body's immune system?
Professor Liang Qianjin from the School of Life Sciences at Beijing Normal University told reporters that T lymphocytes (T cells), which play important roles in the human immune system, are derived from pluripotent stem cells (lymphocytic cells) in the adult bone marrow or the yolk sac and liver of the embryo. After differentiation and development in the thymus, T cells are distributed through the lymphatic and blood circulation to the immune organs and tissues of the body, and assume the function of immunity.
"It should be pointed out that T cells are of course not 'normal cells' on the surface or in the contents of the cells. There are many surface antigens and surface receptors on the cell membrane of T cells, and on the cell membrane. A special marker for the binding of giant protein molecules. Moreover, different T cells can also perform different functions." He introduced, for example, cytotoxic T cells as "killers" or cytotoxic agents that can kill targets with specific antigenic responses. Cells, while memory T cells, play an important role in the re-immune response.
Xuanzhi medical nanotechnology is still in the experimental stage
The functions of T cells and the entire immune system are complex, both from the occurrence and maturation of immune cells, to the acquisition of specific markers, and to the creation of unique functions. The mysteries are numerous and are not fully resolved. Professor Liang said that it is very difficult to simulate or replace immune cells or immune systems with artificially created tools. Just as disease treatment is actually a synergistic effect of medical means and drugs and the human body's own conditions, the medical methods produced by nanotechnology and the like must be matched with the physiological or molecular physiological functions of the body to be effective.
"Although genomic research generally reveals the scale of human genes, the results of gene function research are endless, but it is still far from fully analyzing the nature and genetic characteristics of human genes. Under such conditions, artificially created products are used to solve all complex genetic control. The goal of physiological and pathological problems is not easy to achieve." However, Professor Liang believes that this does not affect people's targeted "microsurgery" for diseases that have a clear pathogenesis, or that have a clear molecular mechanism.
Just as we have common sense, people will not think about "life is not old", but have confidence in the prospects of prosperous medical care, precision medicine and preventive care. Professor Liang told reporters that the prospects of nanomedicine technology in this regard are considerable. As an emerging technology in robotics engineering, the technology for developing nano-robots belongs to molecular nanotechnology. This technology uses molecular biology at its molecular level as a prototype to design and manufacture "functional molecular devices" that operate on nanospace events. Nanomachines can be injected into human blood vessels for health checkups and disease treatments, which will surely become more and more beneficial to medical care.
"For the time being, medical nano-robots are still in the experimental stage. Nano-machines are used to protect human health, and there is still a long way to go. We are cheering for technology and engineering people engaged in nanotechnology research!" he said.
