Today the world is becoming more and more modern, science and technology have developed very fast and new things have been provided to man. Man is using thousands of facilities at home through computer and internet and many tasks can be done in minutes and seconds. Nanotechnology is one of the fastest growing technologies in this modern age. Progress has been made to predict what it will look like in the future.


 Nanotechnology is the manipulation of matter on the nano scale. Nanos are objects that are about a million times smaller than the tip of a needle. If we measure the length of a row by placing three or four atoms in a row, it will be one billionth of a meter, which we call a nanometer. So if we invent material objects that hold the atom in a certain place. Install then this is really nanotechnology.


 Some scientists believe that many of the revolutionary inventions in science and technology in the 21st century will be due to nanotechnology. This clearly shows that in the late twentieth century, information technology In the 21st century, nanotechnology will revolutionize the world. According to experts, every technology can change because of nanotechnology. Its future looks very bright.


 The raw materials used in this technology are in fact all the materials that are used in the production of living and inanimate objects as special building blocks or bricks used in the house. The use of substances in nanoparticles is very small. One nanometer is one billionth of a meter. That is, if we add ten atoms of hydrogen one after the other, it will be one nanometer. A DNA molecule is 2.5 nanometers. A blood cell is 5,000 nanometers and a human hair is 80,000 nanometers thick. This shows how nanotechnology works at a very small level.


 Nano not only has a very small size of matter but also its properties change. When the tabane is brought to the nano level, it becomes so flexible that it can be stretched at room temperature to make a wire fifty times longer than ordinary copper. Can be toxic. Through this, many things are being made by combining living cells and substances with inanimate atoms.


 In these circumstances, experts fear that drugs or creams made in this way can penetrate the body's cells and destroy them, damage the DNA or destroy the blood-brain barrier. However, this border between the brain and the blood is difficult for drugs to cross. While many people are happy with the use of this technology in food and medicine, scientists and environmentalists are concerned. Experts warn that as this technology becomes more powerful, its effects on human society will increase. Will become just as universal.


 Paul Seifo, a professor at Stanford University, says it is important that we formulate policies on the use of nanotechnology. He believes that the lessons we have learned from the atomic bomb and nuclear technology over the past 50 years Are very important We built the atomic bomb first and then the regulations, so that people wouldn't start dropping bombs indiscriminately. The same thing would happen with new technologies. But despite knowing all this, nanotechnology is being given importance, because the advantages outweigh the disadvantages of this technology.


 According to some experts, it has become necessary to make new rules for the proper use of nanotechnology. Nanos are objects that are about a million times smaller than the tip of a needle. It is believed that this technology will revolutionize human life in the years to come. Experts believe that people will be amazed at the batteries that will run out in three days after just a few years, because nanotechnology has made batteries that last for many years.


 Scientists at MIT University in the United States believe that in a few years, nanotechnology will make it easier for US troops to move supplies from one place to another. Where at present a soldier has to carry a load of 10 or 15 kg, in a few years it will be reduced to 10 or 15 kg. According to a report by the Royal Society and the Royal Academy of Engineering, However, the report also acknowledges that it can have some side effects, especially small objects or nanotube particles that can enter the human body when you breathe. By using nanotechnology, atoms and molecules can be used to give different objects extraordinary roles.


 A report by the Royal Society and the Royal Academy of Engineering recommends that nanoparticles and nanotubes be given the status of new chemical products under British and European law. They must be certified by an independent scientific safety committee before being included in consumer goods. The report examines the impact of nanotechnology on the environment, human health and safety.


 Proponents of the technology say it could be useful for medical and industrial research. He says the extraordinary role of objects on a very small scale can be used to make better machines, but there are many misconceptions about this science. Some people think that this technology Because machines smaller than a virus will take over the world and destroy it. According to experts, such things are completely wrong and imaginary.
