What is nanotechnology?Md Emon
Nanotechnology refers to the science and technology of Nano-measuring objects, the objects that make up the display significantly different religions than the ones shown on a large-scale or even microscopic scale. In 1959, the famous American physicist Richard Feynman first described the concept of nanotechnology in his “There’s Plenty of Room at the Bottom”. Where he described the likelihood of synthesis through direct manipulation of atoms. That’s why Feynman is named the daddy of nanotechnology. In today’s article, we are going to know about nanotechnology. So, let’s start without any delay!

History of nanotechnology
On January 29, 1959, Richard Feynman first introduced the concept of nanotechnology at a meeting of the American Physical Society held at the California Institute of Technology. November 9, 1989, will be one of the most memorable days for nanotechnology. On this day, Don Eigler and Erhard Schweizer created the IBM logo with 35 Xenon molecules at IBM’s Almaden Research Center in California. On the same day, human beings can make the desired choice by arranging the first molecule at will. It was on this day that the first man was able to break the molecular structure of nature’s most important foundation. Many things can be done by making the structure of the molecule as desired. The door of a huge possibility was opened before the people. Coal is so cheap and diamond is so expensive just because of the structural differences in the molecules. The main component of the two things is carbon. Diamonds are the hardest material in the world and coal or pencil sheets are the softest because of differences in molecular structure.
In 1999, Wilson Ho and his student Hyojune Lee at Cornell University demonstrated the process of pairing molecules. Until now, atom-to-atom bonding was organized only through chemical reactions. Through nanotechnology, the door has been opened to the possibility of doing many things by breaking or attaching molecules.
Uses of nanotechnology
- Medicine: At present, researchers are directly removing the diseased cells of your body by supplying drugs, which are being used more and more in the treatment of cancer. In the future, nano-medicine will benefit in molecular nanotechnology. Nano-science applications have many predictable advantages in the medical field and have the potential for all humankind.
- Electronics: With the help of nanotechnology, the capacity of various electronic devices is increasing and their power consumption, as well as weight, is being reduced. The use of nanotechnology has made the electronic field promising.
- Food: In addition to food science, there are significant uses of nanotechnology in how food can be grown and packaged. The package of chips we see also has the use of nanotechnology. It will make a difference not only in the taste of food but also in food security and the health benefits that food provides to future generations.
- Fuel: Nanotechnology is being used to make hydrogen ions from fuels like methanol and to reduce the cost of catalysts used in fuel cells.
- Hardware: Nanotechnology is related to computers. The processor inside the computer is made up of countless tiny nanometer-scale circuits. And nanotechnology is being used in it. In Intel processors, the circuit is patterned on silicon and its current size is 100 nanometers. In the future, its size will be 50 nanometers. The ability to store information on a computer’s hard disk is increasing day by day due to the application of nanotechnology.
Nanotechnology is also being used in spacecraft, chemical sensors, sporting goods, etc.
Nanotechnology in Covid-19
Scientists at the Max Planck Institute (MPI) claim that their nano-body or Göttingen nano-body is effective against the SARS-COV-2 virus and can bind and inactivate the virus 1000 times better than previously created nano-bodies. Since the nano-bodies are very small, they can easily penetrate tissues and prevent the spread of the virus. That’s why researchers hope to use this nano-body in the general treatment of Covid-19.
Disadvantages of nanotechnology
The main problem in making circuits with nanotechnology is static electricity. Ordinary electric circuits have a system to protect the circuit from this static electricity. If that were not done, static electricity would ruin the electrical equipment for some reason. But in the field of nanotechnology, electrical circuits become unimaginably small, so it is not possible to protect them traditionally. In fact, in a short circuit, static electricity produces heat of about 15,000 centigrade. This heat can melt the circuit’s components, destroying the circuit. For this reason, copper has been used instead of the conventional aluminum used in IC circuits since 1997. Because copper has a melting point of 1083 whereas aluminum has a melting point of 6600 centigrade. As a result, even at higher temperatures, copper will work better than aluminum. Nanotechnology is expensive. As a result, the products produced by the application of this technology are expensive. Another big problem is that some nanoparticles are harmful to the human body.
The world towards nanotechnology
At present, scientists are paying more attention to nanotechnology Because the successful application of nanotechnology will make it easier to use electronic products starting from medical science Severe disorders like cancer can be cured without any cuts or tears in the body You can fold a computer and carry it in your pocket There will be pictures with so many fine cameras that I may not be able to read And with the application of nanotechnology, food grains can be made several times more nutritious Maybe eating a cup of nano-nutritious food will cut the curse all day long Scientists are continuing to make these possibilities a reality
The first international scientific conference on various aspects of nanotechnology was held in Karlsruhe, Germany the conference discusses the components of metallurgy that are being used in nanotechnology. Scientists also discussed various aspects of the application of nanotechnology to meet the demand for energy, In particular, scientists are looking for alternative fuels to prevent climate change As a result, nano-energy is now being considered as one of the alternative fuels
The conference was attended by Rezaul Karim, a Bangladeshi scientist studying nanotechnology in Istanbul, Turkey. On the benefits of nanotechnology for mankind, Karim said nanotechnology could be used extensively in medical science. It will be useful for the treatment of cancer Besides, if you can apply nanotechnology, you don’t have to do open heart surgery If the heart was blocked, surgery would be done or a ring would be worn But now we can open these blocks only if we insert nanoparticles through the arteries and control them from the outside with biosensors. Can be used in electronics, For example, if we can use nano solar cells in mobile phones, iPods or computers, they will become much smaller.
Just as the great discoveries of science have brought blessings to the world, so too have catastrophic events taken place at different times. There have been nuclear accidents and misuse of atomic bombs According to Rezaul Karim, special steps must be taken to ensure that nanotechnology does not cause such harm to human society.
