Nanotechnology

 Nanotechnology

Have you ever heard the term nanotechnology? This technology is very unreasonable because it can turn something into something unreasonable like a fiction film. Nanotechnology is a technology smaller than a virus, but it can change everything. Not only that, we will discuss nanorobots.

This technology is a manifestation of real-world technological change, because technology is increasingly moving towards becoming more portable. The example is; The first computer of World War II was very large and difficult to operate. Evolved into a "personal computer" that we can operate and is more portable. Then laptops appeared, namely computers that we could take anywhere and now we can hold computers in the form of smartphones.

Why did it happen? because transistors, which are the main component in computers, continue to shrink 2x from before every year. Initially, transistors were shaped like tubes and continued to get smaller until semiconductor technology emerged. Therefore the size of the transistor can be smaller than the diameter of a human hair. So a chip on a smartphone that is no bigger than a thumbnail can contain billions of transistors. Currently, the smallest size of a transistor is 5nm, close to the size of human DNA which has a size of 2nm.

 Nanotechnology

This is nanometer scale technology. The way to calculate nanometers is by dividing 1 meter by 1 billion. If a strand of hair is 100,000nm, then you have to split a strand of hair 100,000 times. That is the size when we have touched the world of molecules or atoms, which are impossible to see with the naked eye. You have to use a Transmission Electron Microscope (TEM) or what we often call an electron microscope.

Nano robot

Nanobots are basically an arrangement of molecules that are specially designed to have certain movements. Like Rice University which designed a nano-car, the shape is similar to a car but the base is an arrangement of hydrogen and carbon atoms. And what's even more exciting, there is already an official national level nano-car race! where the participants are researchers from various countries to design nano-cars, then compete in speed races like Tamiya races.
