Introduction To Nanotechnology. - Meaning of Nanotechnology

Introduction To Nanotechnology :

We all see dreams, our elders say, dream big dreams. But if we talk about 'small' dreams instead of big dreams! Let us imagine a future when computers will work faster, steel will be made lighter but a hundred times stronger than it, and diseases like Parkinson's and AIDS can be treated with the help of special medical tips.

This is not a dream or a fantasy of any science fiction, but all these possibilities with nanotechnology or nanotechnology working at the level of molecules and atoms are going to turn into reality in the future.

Introduction To Nanotechnology 

Actually, science of super-sized particles is called nano science. Since technology is a means of making science useful, nanotechnology is actually the only practical form of nanoscience. Scientists say that nanotechnology has more tips, equipment, etc. than micro, less space occupying and current tips. Will become more efficient.

In such a situation, it will become easier to handle the business of this world. It will also be easier to get more energy efficiency and to create environment friendly conditions, let's try to know what Nano actually is?

 Meaning of Nanotechnology:

The word Nano derives from the Greek language 'nanose' which means dwarf. Therefore, nanotechnology can also be called dwarf technology. Micro Technology Micro Technology) we use to manufacture micro and advanced computers. But nanotechnology works on a more subtle level than micro technology.

Scientists are engaged in making nano robots that will be able to enter the human body and perform superficial operations. For this, it will be possible to construct biologically important molecules with the help of nanotechnology. Such biomolecules can be used in industrial and medical applications.

Let us now see how subtle Nano is. In terms of measurement, nano represents one billionth, as one nanometer means one billionth of a meter. How subtle the nanometer is can be estimated by the fact that it is equal to one millionth of an allpin knob.

A length made up of ten hydrogen atoms, or six carbon atoms, will also be one nanometer. Similarly, if we imagine something about 90,000 times thinner than human hair, it will be equal to one nanometer; That is, the thickness of our hair is about 90,000 nanometers.

The size of a small ant is about 5 million nanometers. The diameter of a human cell is 30000–50000 nanometers while the diameter of the cell nucleus is nanometers. In contrast the thickness of DNA is only 2 nanometers while the size of proteins is 1–10 nanometers.

But it would be a mistake to explain nanometer as the last step of precision. For example, the first angstrom unit used to measure the wavelength of light is equal to ten-billionths of a meter, i.e. one angstrom is equal to 0.1 nanometers.

Come, starting from one meter, descending the step of subtlety to nanometer. The first millimeter will come in our journey, which is one thousandth of a meter. After this will come the micrometer which is one millionth of a meter and after that the nanometer which is one billionth of a meter.

The thing to note is that after reaching one to three steps from a meter, we reach nanometer. On descending each of these steps, the value of precision is reduced by a thousand times. In comparison, the knob of a pin is equal to one millimeter, the size of an initial bacterium is one micrometer and the length of ten hydrogen atoms or six carbon atoms is equal to one nanometer. it occurs . If we continue this journey beyond nanometer, then another step will come first picometer (10-12 meters), then femtometer (10-15 meters) and then atometer (10-18 meters).
