The ideas and concepts based on nanotechnology and nanoscience were put forward by Nobel Prize-winning physicist Richard Feynman on December 29, 1959, during a meeting organized by the American Physical Society (APS) at the California Institute of Technology (CalTech). In his speech, Feynman mentioned the uniform potential of controlling matter at the atomic level and stated that the knowledge we have is approaching this level day by day.
The word nanotechnology was coined about ten years later by Prof. It was invented by Norio Taniguchi. The beginning of modern nanotechnology in a real sense was realized with the invention of scanning tunneling microscopy in 1981, which allows us to see atoms. In the post-millennium world, nanotechnology seems to have become one of the most invested areas. America allocated $1.4 billion to nanotechnology in the 2017 Federal Budget for Dec Dec research and development, and a total of $24 billion has been used in R&D activities since 2001.
The Impact of Nano Technology on the Profession
Nanotechnology has contributed to major advances in computer and electronic technologies by enabling the development of systems that are faster, smaller, portable and capable of storing more data. Transistors, the simple switches that enable all modern computers to work, are getting smaller and smaller thanks to nanotechnology. At the beginning of this century, the size of a transistor was between 130 and 250 nanometers, while in 2014, Intel developed a transistor 14 nan Decometers tall. IBM created the first 7-nanometer transistor in 2015, and Lawrence Berkley National Laboratory introduced a 1-nanometer transistor to the world in 2016. Smaller and faster transistors may soon enable all the memory of a computer to be placed on a single small chip.

Electronic items that can be stretched, bent and folded have gradually started to enter our lives. Developments such as flexible phones, foldable electronic papers, photovoltaics that can be sewn to clothes (technology that converts light into electrical energy) increase our quality of life. The very high-resolution screens and televisions currently on the market use quantum dots (QD) that are only a few nanometers in size and consume much less energy while delivering much more vivid colors. Nanotechnology is expanding and improving the medical tools, knowledge and methods that we currently have. Nanomedicine offers definitive results for the application of nanotechnology to the medical field, prevention, diagnosis and treatment of diseases. Gold nanoparticles are being clinically investigated as a potential cancer treatment. Better imaging and diagnostic tools created thanks to nanotechnology are paving the way for earlier diagnosis of diseases and the use of personalized treatment options.
Nanotechnology will enable the pollution in the water to be detected and cleaned with low cost, enabling the need for clean and cheap drinking water to be met Jul. Nanoparticles have been developed that make industrial pollutants in groundwater harmless by chemical reactions. This process is much cheaper compared to pumping water out to be cleaned. Researchers have produced nano-fabric “paper towels” knitted with small wires from potassium manganese oxide. These towels have the capacity to absorb oil twenty times their own weight. The air filters used in airplane cabins are filters that perform “mechanical filtration” produced by nanotechnology. The fiber materials inside the filters have pores on the nanoscale and do not allow the passage of larger particles. In addition, the charcoal layers of the filters prevent the passage of the odor. Sensors and solutions made with nanotechnology identify chemical or biological agents in the soil and air much faster and with great precision than before. A sensor developed by NASA allows firefighters to measure the air quality around fires via a smartphone extension. Engineers have made energy-efficient desalination (desalination) possible with thin-film membranes with pores that they have developed. This membrane, named molybendum Deculphide (MoS2), filters two to five times more water than normal filters.
Nanotechnology has been entangled in more than one profession in human life in the form of a spider's web and positive results have been obtained.
