What Is Nanotechnology
Nanotechnology is the application of science, engineering, and technology on the nanoscale, or between 1 and 100 nanometers.
Richard Feynman, a scientist, has developed nanotechnology.
Nanoscience and nanotechnology, study and use extremely small objects.
It also applies to all other scientific disciplines, including chemistry, biology, physics, materials science, and engineering.
How It Started
Long before the term “nanotechnology” was coined, physicist Richard Feynman gave a talk titled “There’s Plenty of Room at the Bottom” at an American Physical Society meeting at the California Institute of Technology (CalTech) on December 29, 1959,
This laid the foundation for the theories and concepts that would later become the basis of nanoscience and nanotechnology.
In his lecture, Feynman presented a method for how scientists would be able to control and manipulate specific atoms and molecules.
Professor Norio Taniguchi first used the term “nanotechnology” in his studies of ultraprecision machining more than ten years later.
Modern nanotechnology didn’t start until 1981, when the scanning tunneling microscope was created, allowing scientists to “see” individual atoms.
Use of Nanotechnology in Electronics and IT Applications
Nanotechnology has allowed transistors, the fundamental switches that enable all contemporary computers, to get smaller and smaller.
A typical transistor at the beginning of the century ranged in size from 130 to 250 nanometers.
Intel created the first 14-nanometer transistor in 2014, and IBM created the first seven-nanometer transistor in 2015.
Lawrence Berkeley National Laboratory created the first one-nanometer transistor in 2016!
With smaller, faster, and better transistors, your entire computer’s memory may eventually fit on a single chip.
Computers will be able to “boot” almost instantly using magnetic random-access memory (MRAM).
MRAM, which can efficiently save data after a system shutdown.
It enables resume-play features and is made possible by nanoscale magnetic tunnel junctions.
Quantum dots produce brighter colors with less energy and are useful in ultra-high-definition displays and televisions.
Other computing and electronic products include flexible displays for e-readers, Flash memory chips for smartphones and thumb drives, ultra-responsive hearing aids, and antimicrobial and antibacterial coatings on keyboards.
It is also useful in cell phone casings and printed electronics for RFID, smart cards, and smart packaging.
Lead-based solders and other potentially hazardous materials are being phased out of the assembly process in favor of safer, less expensive, and more dependable nanoparticle copper suspensions.
Use of Nanotechnology in Medical and Healthcare Applications
Nanotechnology is already broadening the medical tools, knowledge, and therapies currently available to clinicians.
Nanomedicine, the application of nanotechnology in medicine, draws on the natural scale of biological phenomena to produce precise solutions for disease prevention, diagnosis, and treatment.
