For many years there is a hype about nanorobots, tiny computers, high-speed processors with power efficiency, smart portable devices. The basic technology used in these products are of Nanomaterials.
Lets talk about the Future of Nanotechnology
What is Nanotechnology?
Nanotechnology is a study of various scientific materials and its applications on a nanoscale (atomic, molecular level). It uses the concepts of nanoscience. Nanomaterials are used in the research and development of this technology.
Nanoscience is not a new term, we are using it from past 20-30 years in processors, circuit boards to develop small chips that can fit into small and portable devices. Although processors and chips that uses nanotechnology is small, it can have high processing power because of its efficiency towards energy consumption.
But the main issue in the development of nanomaterials is that when a particle is so small in the subatomic state, the properties also change. Hence, the normal principles we use in daily life are not applicable.
General laws of physics doesn’t hold good for so small materials that are in atomic or subatomic state. Quantum physics might solve this issue in the future.

What is a Nanomaterial?
Nanomaterials are the material that has a size between 1nm to 100nm which can be used for innovating small devices at the microscopic level. Presently, the best example of nanomaterial is ‘Carbon nanotubes‘ which are almost 100 times stronger than steel and has a diameter of approx 0.5–40 nm.
If you compare carbon nanotubes with a sheet of paper or a human hair, these nanotubes will be unbelievably small in size. A sheet of paper is 100,000nm and human hair is 800,000nm. Just imagine how small a carbon nanotube of 1nm would be.
“As technology advances, the world is shrinking.”
How did the Idea of Nanotechnology come into existence?
The concept of nanotechnology was first introduced by a Physicist Richard Feynman. During his lecture, he said this statement that “There’s plenty room at the bottom”. Further, in 1959, an American physicist from the Calfornia institute of technology gave the idea which became the basis of nanotechnology.
After a decade, Professor Norio Taniguchi used the term nanotechnology. Later in 1981, When the electron microscope was invented, Since then nanotechnology research has been going on.
So, now we know what is nanotechnology and its history, the question arrives that why is nanotechnology so important?
Why Nanotechnology is important?
The major benefit of Nanotechnology is that the products made from it will be very very small in size, light in weight, and will be comparatively cheaper. Besides, the raw materials for products would be less and energy requirements will also be reduced.
We can overcome many serious health problems and diseases through this technology. With the help of this technology, there will be a boom in the field of bioscience, medical science, and electronics.
5 Real-world applications of Nanotechnology
1. Nanotechnology for cancer treatment and vaccine delivery: By taking the help of this, such micro-drugs can be made which can prevent cancer cells from our bodies. By identifying cancer cells, it will be able to treat them separately. With the help of this technology, the molecular assembling of any material can be easily understood.
2. Manufacturing manures and fertilizers: It can be used to make manure through which crop production can be increased rapidly. This can lead to healthy plant growth, but if it is used excessively it can damage the soil and plants. Check out this article to know more about how nanoparticles used for plant growth.
3. Pollution control: With the help of Nanotechnology, toxic fumes discharged from industrial areas and vehicles can be converted into a harmless gas. This results in a rapid decrease in air pollution.
4. Portable Nano computers: Who would have ever thought that we can hold a computer in our hand and move around. A few decades ago it was quite impossible to make a computer so small. Computers in the ’90s were so slow, huge, and chunky that it would fit a room. This is made possible due to the evolution of microprocessors. In 2000 the size of transistors was 250nm and now it has reduced to almost a single nanometer, due to this small nanoscale junction there is a drastic improvement in the performance of a computer.
5. Nanobots: The emerging future and hype about Nanotechnology are only because of nanobots. These are tiny nanorobots that can be inserted inside our body to deliver vaccines or to check the status of disease affecting areas and destroying it from inside. They can also be used as artificial antibodies, antiviral nanobots that can operate for years without damaging the body.
But researchers are still working on these nanobots and how to remove these bots after the completion of the task from the body. It will be possible shortly.
There are many more applications and uses of nanotechnology like flexible displays, high-speed processors, semiconductor membranes, future gadgets like wearables, smartwatches, nano suit, etc…

Future of Nanotechnology
Now, You might have understood about what is nanotechnology and how it can make our life comfortable and advanced.
Although there are so many benefits of Nanotechnology, there are some huge cons that would be a concern and might make you think about this technology growth like, what would happen if the development of nanotechnology is done for a wrong purpose? – It can lead to health issues, security problems, and more.
Rather than all that, I support the evolution of nanotechnology which can be used to reshape the future.
I know it’s still under development phase and requires few years or more to make it completely applicable to the real world.
But if you ask me what interests me so much in nanotechnology?
After watching Avengers: Infinity war, I want to use a nano suit similar to that of Tony stark, which has to be completely functional and can make science fiction into reality.
