Nanotechnology and its useful applications

The term nanotechnology is very popular these days, surely everyone has heard of it. But not everyone knows what nanotechnology really is.

What is nanotechnology?

Nanotechnology is a technology industry related to the design, analysis, fabrication and application of structures, devices and systems by controlling shape and size on the nanometer scale (nm, 1 nm = 10−9 m).

This technology is also considered cleaner (less polluting) and more efficient than current technologies.

Nanotechnology has a huge application in life and is a promising technology both now and in the future. Imagine having small nano-sized devices that can go inside the human body, find "sick" parts and even better, contribute to making those parts "healthy" again. This technology is also considered to be cleaner (less polluting) and more effective than current technologies.

Applications of nanotechnology

1.Nanotechnology can save your life

Medicine is one of the biggest applications of nanotechnology. For example, in the treatment of cancer, many different treatments have been tested to limit the growth of tumors and destroy them at the cellular level. One study has shown very positive results when using gold nanoparticles to fight many types of cancer. These nanoparticles will be delivered to tumors inside the body, then they are increased in temperature by infrared laser beam from outside to destroy the tumors.

Medicine is one of the biggest applications of nanotechnology.

Not stopping there, scientists are also researching a very special nanorobot project. With robots of super small size, they can go inside the human body to deliver treatment drugs to the necessary parts. Providing drugs directly like that will increase the ability as well as the effectiveness of treatment.

Nanotechnology in the near future will help people fight against the terrible disease of cancer. Even the most difficult cancers such as brain cancer, doctors will be able to easily treat without opening the patient's skull or any toxic chemotherapy methods.

2. Nanotechnology in electronics around us

Nanotechnology also contributes significantly to the field of electronics, especially energy technology.

When you think of nanotechnology, you may think of scientific projects being conducted by leading professors in laboratories, the most advanced and advanced technologies. However, in reality, you may be using some nanotechnology products right now. Microprocessors made from nano materials are quite popular on the market, some products such as mice and keyboards are also coated with antibacterial nano layers.

Nanotechnology also contributes significantly to the field of electronics, especially energy technology. Future nano batteries will have a structure like nanowhiskers. This tube structure will make the battery poles have a much larger surface area, helping it store more electricity. Meanwhile, the size of the battery will be increasingly narrowed.

3. Nanotechnology in garment applications

The fashion industry has turned a new page with the application of nanotechnology in some special fabrics.

Since the early 2000s, the fashion industry has turned a new page with the application of nanotechnology in some special fabrics. A very special idea with clothes that can kill bacteria that cause unpleasant odors in clothes has become a reality with the application of silver nanoparticles. These silver nanoparticles can attract bacteria and destroy their cells. This useful application has been applied to some sportswear models and more specifically, used in a type of deodorant underwear.

Not only does it deodorize, nanotechnology can turn the shirt you are wearing into a mobile power station. Using energy sources such as wind, solar energy and with nanotechnology you will be able to charge your smartphone anytime, anywhere. This application is also widely used with the idea of ​​​​making sails from nano materials, with the ability to convert natural energy into electricity. However, this application is still in the testing phase.

4. Nanotechnology in nature

Applications of nanotechnology can be found in nature today.

It is a fact that the applications of nanotechnology can be found in nature today. For example, an application of nanotechnology on fabrics makes them waterproof and dirt-repellent, you can see the same thing when water droplets roll on the surface of a lotus leaf. The surface of the lotus leaf is covered with a special layer of nanometer-sized hairs, making it impossible for water droplets to penetrate or stick to the surface of the leaf. Simulating this, scientists have created a layer of microscopic nanotubes on the surface of fabrics and thereby created waterproof and dirt-repellent clothes.

An example of this is gecko, which is part of a project by Robert Full’s team at Berkeley to develop a wall-walking device. Scientists have discovered that each of the gecko’s toes is covered with microscopic hairs that help it stick to smooth surfaces using van der Waals forces (the adhesion between molecules). By mimicking this, scientists have also created pads with microscopic nanotubes that could help rock climbers grip cliffs better.

Human society is very developed today, however we are still learning a lot from nature. The important thing is that the development of scientific technology must contribute to promoting life, not destroying the life of nature.

5. Food from nanotechnology

Nanotechnology will also help preserve food longer.

Nanotechnology is the study, analysis and design on a very small scale of nanometers, so if we use nanotechnology to make food, how much of it will be enough to make us full? Fortunately, we will not eat food made from nanotechnology, but nanotechnology will change the way we eat everyday dishes.

Scientists have been experimenting with changing foods at the atomic and molecular level, making them taste better and more nutritious. This means we can enjoy dishes with unique flavors and high nutritional value thanks to food nanotechnology.

Nanotechnology will also help preserve food for many times longer by creating food containers that have the ability to kill bacteria. We can see many types of refrigerators today are coated with a layer of nano silver inside to kill bacteria. Even some high-end food cans today are also coated with a layer of nano silver inside.

6. Nanotechnology and the future

Nanotechnology has huge potential.

Scientists all affirm the role of nanotechnology. However, not every field can apply this technology. Behind it is a series of related factors such as ethics (when using nanotechnology to intervene in genetic modification), social factors and human factors.

"Nanotechnology has enormous potential. It can bring many benefits in many different areas. However, we must consider it from a different perspective, in terms of ethics, health, safety and societal response," said Lord Sainsbury, UK Science and Technology Minister.

Therefore, the UK has quickly researched the development possibilities of this type of technology and put them into strict application regulations. However, scientists predict that in the near future, nanotechnology will dominate most of the main fields of human science.
