What is Nanotechnology?
Nanotechnology is the field that deals with the materials of nanoscale. The National Nanotechnology Initiative calls it “nanotechnology” if only, “the research and technology development at the atomic, molecular or macromolecular levels, in the length scale of approximately 1-100 nanometer range, creating and using structures, devices and systems that have novel properties and functions because of their small and/or intermediate size and ability to control or manipulate on the atomic scale”. This technology combines principles from various fields, including physics, chemistry, biology, and engineering, to create structures and devices with enhanced characteristics.
The process of nanotechnology involves several techniques to create and manipulate materials at the nanoscale. One common method is bottom-up synthesis, where smaller units like atoms or molecules are assembled into larger structures. Another approach is top-down fabrication, which involves breaking down bulk materials into nanoscale components using techniques such as milling or etching.
Physicist Richard Feynman introduced the concept of nanotechnology during his talk titled “There’s Plenty of Room at the Bottom” at an American Physical Society meeting at Caltech on December 29, 1959. In his talk, he envisioned that the entire Encyclopedia Britannica could be printed on the head of a pin. Although scientists had worked with nanoparticles for many years, their research was largely limited because they couldn’t see the nanoparticles themselves.
Be that as it may, nanotechnology is important because it has the potential to drive significant changes in many aspects of our lives. With applications ranging from targeted drug delivery systems in medicine to more efficient energy solutions, the knowledge of how nanotech works can inform better decision-making and foster innovation.
