Nano Technology

Today the world is changing from modern to modern, science and technology have evolved very Development and new things have been provided to man. Humans are using thousands of home-based services through computers and the Internet, and many tasks take place in minutes and seconds. Technology is becoming increasingly popular in nanotechnology. The speed with which this technology has evolved over the past few years can be gauged from what form it will take in the future.

Nanotechnology is called manipulation of material at the nano scale. Nano refers to 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 a billionth of a meter, which we call nano materials. So if we invent material that has the atom in a fixed place, then this is actually nanotechnology. Some scientists believe that there will be revolutionary inventions in the field of science and technology in the 21st century, many of these will be due to nanotechnology. This clearly shows the revolution that took place in the world of information technology at the end of the twentieth century, nanotechnology will bring about even greater revolution in the 21st century. According to experts, nanotechnology can change every technology. Its future looks very bright.
The raw materials used in this technology are actually materials that are used as bricks in a particular building block or house in the birth of lifeless and non-living objects. Nanotechnology is used on a very small scale. A nano meter is a billionth of a meter. That is, if ten atoms of hydrogen were added one after another, that would be a nano meter. A blood stem is five thousand nano meters and a human hair is 80 thousand nano meters thick. This shows how nanotechnology works on a very small scale. Nano not only has a very small size of material, but also changes its properties. When the radiation is brought to the nano level, it is so flexible that it can be pulled at a room temperature by fifty times longer than ordinary copper. Simple and harmless substances can be very poisonous to the level of nano. Many materials are being made by combining lifeless cells and substances with lifeless atoms. In these cases, experts are warning that this type of drug or cream can penetrate the body's cells and destroy them, may damage DNA or eliminate blood borne barriers. However, crossing this border between the brain and the blood is difficult for medicine.While many people are happy with the use of this technology in food and medicine, scientists and experts are worried. Experts have warned that the more powerful this technology becomes, the more its effects on human society will grow.

According to some experts, new rules have become necessary for the proper use of nano
technology. Scientists at MIT University in the US believe that in a few years, nanotechnology will make it easier for US troops to move goods from one place to another. Where a soldier has to carry a load of 10 or 15 kilograms at this time, there will be only 10 or 15 grams after a few years. According to a report by the Royal Society and the Royal Academy of Engineering, nanotechnology can be of great benefit to humanity. However, the report also acknowledges that it may have some side effects, especially the small substances Yanino Tube Particles that enter the human body while      breathing. Different materials can be given extraordinary role by using atoms and molecules with nanotechnology.
Supporters of this technology say it will be very useful for medical and industrial research. They say that the extraordinary role of small objects can be used to make better machines, but there have been many misconceptions about this science. Some people believe that this technology will destroy even the smallest virus machines by occupying the world. Experts say such things are completely wrong and hypothetical.
