What is Nanotechnology?
The word Nano comes from the Greek Nanos which literally means Dwari (dwarf or miniature creature with magical powers) but is used as a unit of measurement. 1 billionth of a meter is a nanometer. And all the technologies related to the nanometer scale are called nanotechnology. Nanotechnology is the science, engineering, and technology that operates at the nanoscale, which is 1 to 100 nanometers. Through this technology, many things can be done in the future by connecting molecules and atoms.
Nanotechnology is the science of manipulating metals and materials to create microscopic devices (eg, robots) at the atomic or molecular scale.
How does nanotechnology work?
When we get into the nanoscale, we get to work in areas of physics that wouldn't normally be possible. The objects around you are made of anu. The way those links are arranged determines what the object will do. With nanotechnology, the functional space can be smaller than 100 nanometers. Nanotechnology is the study of controlling matter at the nuclear, atomic and sub-molecular levels.
Generally, nanotechnology is conducted on a scale of 1 to 100 nanometers. Through nanotechnology, something can be made so small that
If a 1 centimeter ball is one nanometer then the size of the earth is one meter. Nanotechnology allows materials to be made so small that they cannot be made any smaller. Everything in this world that we eat, what we wear, the houses we live in, everything in our body, etc. is made up of atoms. But atoms are so small that they cannot be seen with the naked eye. In 1980, IBM researchers first discovered STM (Scarutning Tunneling Microscope) with this device it is possible to see the structure of molecules. It was the invention of this device that made nanotechnology a reality.
Many things will be possible to do in the future by breaking or joining molecules through nanotechnology. There are two processes in nanotechnology. One is top to bottom and the other is bottom to top. In the top-down method, an object is cut down to a certain size. This field is usually related to the Etching process. And bottom to top is about making big things out of tiny little things. Our current electronics are top to down technology. Nanotechnology (Nanotechnology) is bottom to top technology. With the help of nanotechnology, any desired object can be made from tiny objects on the nanometer scale.
Who is the inventor of nanotechnology?
American physicist Richard Feynman first proposed nanotechnology in his talk "There's Plenty of Room at the Bottom" on December 29, 1959. Richard Feyman is the inventor of nanotechnology.
Application fields of Nanotechnology
Currently, nanotechnology is being used in the manufacture of various types of products. Some of the applications of nanotechnology are mentioned below:
Computer Hardware Manufacturing : Nanotechnology is used in the manufacturing of various hardware and video games consoles to increase computer memory, speed, efficiency, etc.
Nano Robots : Research is going on to create very small robots using nanotechnology. Such robots will be able to perform surgery inside the human body.
Electronics Devices : Nanotechnology is used in the manufacture of various types of devices with the aim of increasing performance by reducing power consumption, weight and size. Nanotechnology is used to produce fuel from low-cost raw materials and fuel cells for use in various types of batteries and hydrogen.
Cancer diagnosis and treatment : Using nanosensors, it has become possible to completely detect cancer-causing biomarkers in the blood of the human body. Cancer cells can be destroyed by using nano needles to precisely apply drugs only to cancer cells.
Sporting goods : Nanotechnology is used to increase the stability of tennis balls, to maintain the position of golf balls in the air, to increase the strength and durability of brackets. Nano technology is also used to increase the durability and comfort of players' shoes, socks, trousers etc.
Future of Nanotechnology
The use of nanotechnology will create new horizons in the field of medicine. For example, in cancer treatment, radiation not only damages the affected cells, but also the surrounding healthy cells. This can lead to disability. If nanotechnology is used, radiation can be given only to the affected cells. The use of nanotechnology can bring revolutionary changes in many fields including medicine, electronics, and energy production. In the 21st century, as much as we hear about IT, we hear about this nanotechnology. The majority of the Japanese national research budget is devoted to nanotechnology.
Countries like Europe, America, China, Korea etc. are doing extensive research on nanotechnology. Why is everyone so interested in nanotechnology? A simple answer is that the future will be the era of nanotechnology. Have a heart attack? The nano robot will enter the body and repair all heart problems. The watch will become a computer. Thanks to nanotechnology, things will be much smaller and lighter.
