Nanotechnology and future fears

Technology and man have been together since the beginning of the world. It is a different matter that in the beginning and today’s technology there is a difference between earth and sky. Man made axes and other tools to cut down trees and other objects, which was the earliest man-made technology. Today the world is becoming more and more modern, science and technology have progressed very fast and new things have been provided to man.

Man is using thousands of facilities at home through computer and internet and due to many machines many tasks can be done in minutes and some with just one gesture. The technology that is becoming increasingly popular today is nanotechnology. The pace at which this technology has evolved over the past few years gives an idea of ​​what it will look like in the future.

Nanotechnology is the manipulation of matter on the nanoscale. 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 nanometers. So if we invent material objects in which the atom has a fixed Install it in place so that in fact this is the nanotechnology. This means inventing something that requires every atom to be in its place at all times. This technology is called nanotechnology.

Some scientists believe that many of the revolutionary changes that will take place in the field of science and technology in the 21st century will be due to nanotechnology. It is clear that nanotechnology has developed tremendously in the last few years. Nanotechnology will revolutionize information technology in the 21st century, as it did in the late twentieth century. A revolution that will give a new dimension to every industry and every aspect of life. The state of nanotechnology is such that it can change every technology.

The future of this technology is considered very bright. Still, the question is how safe the products will be. Numerous special studies and reports from various countries have cast doubt on its safety. But one danger is that it could cause serious damage to people’s health and the environment. The raw materials used in this technology are actually 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 ten atoms of hydrogen were added one after the other, it would be one nanometer. A DNA molecule is two and a half nanometers. A blood cell is five thousand 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 material size but also changes its properties. When the tabane is brought to the level of nano, it becomes so flexible that it can be stretched at room temperature to make a wire fifty times longer than ordinary copper. Can also be very toxic.

Through it, many things are being made by combining living cells and matter with inanimate atoms. Equipment made with this technology is available in the market today. Tea, coffee, and foodstuffs have also been made with the help of this technology, from non-stain stains to clothing and medicine to cosmetics and fashion items.

In these circumstances, experts fear that the drug or cream made in this way can penetrate the body’s cells and destroy them, damage the DNA or eliminate the blood brain barrier, however It is difficult for medicine to cross this delicate border between the brain and the blood. While many people are happy with the use of this technology in food and medicine, scientists and environmentalists are worried. Experts warn What’s more, the more powerful this technology becomes, the more widespread its effects on human society will be.

Paul Seifo, a professor at Stanford University, says it is important for us to develop policies on the use of nanotechnology. Are very important

We built the atomic bomb first and then the rules, so that people wouldn’t drop bombs indiscriminately. We still don’t know where this story will end. The same thing will happen with new technologies. But despite knowing all this, nanotechnology is being given importance, because the advantages outweigh the disadvantages of this technology.

Experts say new rules need to be enacted 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 batteries that run out in just a few years and three days will be a laughing stock, as nanotechnology will make 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 only 10 or 15 kg. According to a report from the Royal Society and the Royal Academy of Engineering, Can have many benefits.

However, the report also acknowledges that it can have some side effects, especially the very small Yanino tube particles that can enter the human body when you breathe in. Different objects can be given unusual roles by using molecules.

A report by the Royal Society and the Royal Academy of Engineering recommends that nanoparticles or nanotubes be given the status of new chemical products under British and European law. They should be certified by an independent scientific safety committee before being included in the list. 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 that 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.
