Nanotechnology in our life

 

Nanotechnology has become a popular and fascinating topic nowadays. Our waterproof watches, phones, cosmetics, bags, etc. are made using nano technology. Home paints, clothes, shoes, in which dust does not accumulate again; The thin films used in smartphone displays that are resistant to scratches and dust – are also made with this technology. One day clothes may be made that don't require water, dirt or even washing. Perhaps something will be developed in the medical field that captures and kills disease-causing viruses or bacteria when they enter the body and kills them one by one.

It is obvious how much nanotechnology there will be and has been in this world. Since nanotechnology can be used to create products with desired properties, its popularity is increasing day by day.

We discussed nano technology in detail in this article. So let's begin.

What is nanotechnology?

Nanotechnology or nanotechnology is the manipulation, modification and control of matter at the molecular or atomic level. This is usually done on a scale of 1 to 100 nanometers.

A nano is a small unit of measurement. 1 nanometer = one billionth of 1 meter. But that's a very small number. The diameter of one of our hairs is 50-80 thousand nanometers. So it is clear how small 1 nanometer is. It is even 10,000 times smaller than the blood cells circulating in our body. So nanotechnology is nanoscale technology or nanoscale technology.

History of the invention of nanotechnology

'Richard Phillips Feynman' or 'Richard Phillips Feynman' (11 May 1918 – 15 February 1988); In his lecture entitled Plenty of Room at the Bottom, he shows how the subtle manipulation of the atom can benefit us in many ways in our daily lives. Later, Japanese scientist "Norio Taniguchi" or "Norio Taniguchi" re-introduced the concept of nanotechnology. However, after the invention of the tunneling microscope in 1981, this idea became a reality. Because with this microscope it was possible to see each atom in the substance separately. This is not the end. Next came the invention of the atomic force microscope, which made it possible to observe, measure and control light on an atomic scale. An example of this is atomic animation.

Some examples of nanotechnology

1. Shortening a substance does not change its dharma. For example, if silicon is cut short, it will remain silicon, and if "copper" is shortened, it will also remain "copper". This is basically what is done to make transistors in electronic devices (we know that the more transistors an electronic device has, the more power it has). Because of this, the transistor gradually shrinks. It is possible to place more transistors in the processor of an electronic device and the performance of the device is also increased. Now 16,000 transistors can fit into a hair-sized space.

2. In the field of agriculture, it is possible to create various modified crops by changing the DNA code of various crops. For example, broccoli was created by changing the DNA code of cauliflower. Broccoli is a modified form of cauliflower. In this way, by changing the DNA code of different crops, new varieties are invented, the production capacity of which is several times higher than that of normal plants.

3. Nanotechnology has brought revolutionary changes in the field of medicine. A nano-sized robot is made and inserted into the human body, and the robot is controlled from the outside to destroy various harmful cells. In this regard, scientists are currently thinking about developing nanorobots that can enter the body to identify the cells responsible for aging and make changes in them to slow down the aging process. In addition, these nano robots will perform other tasks when entering the human body. It can be said that the use of nanotechnology in the medical field will move medicine a long way forward.

4. In addition, the layer used on luggage, airplanes, bicycles, spaceships, tennis rackets, folding displays, glass, dust-free dust-free coatings used on touch-skin phones, UP rays, blue light, and even non-stick fried pens used for runners; Which does not allow the food to burn, is also made with the help of nanotechnology.

How Nanotechnology Works

Let's say you want a garment that is waterproof and dustproof, i.e. resistant to water or dirt. So the garment must be made of material that has that quality. If such a substance is not found in nature, a substance with these properties must be created artificially. This is usually done using nanotechnology. By combining substances with different properties, these properties are combined into one substance. This is how nanotechnology works.

Again, what will be the conduct of the subject, or what will be his religion; It is based on how the molecules of this substance are arranged. Since various changes can be made between the molecules of a material using nanotechnology, by changing the molecules of a material we can also change the behavior of that material and use it according to our needs.

Future tasks that are planned to be carried out using nanotechnology

1. Nanoparticles are planned to absorb carbon dioxide from the atmosphere. This will reduce the amount of excess carbon dioxide in the atmosphere.

2. Attempts are underway to build space elevators using carbon nanotubes.

3. Attempts are being made to create nanoparticles that can break down environmental pollutants and release them into the environment.

4. Professor from the University of California Dr. Richard Brutchey and researcher David developed a type of paint using nanocrystals that act as solar panels. This means that this paint can generate electricity wherever it is used in homes, cars, office buildings. However, this paint uses cadmium, which is a toxic substance. So its use is dangerous and not easily available in the market. But if in the future it is possible to replace cadmium with some other non-toxic substance, it will be easily available on the market and everyone will be able to use it. Thanks to this, they can produce their own electricity.

5. In the medical field, nano robots are made and inserted into the human body to treat diseases. This will reduce the amount of medicine used and also reduce the side effects of the medicine.
