What is Nanotechnology?
Nanotechnology deals with structures and materials at the nanoscale, typically ranging from 1 to 100 nanometers. To put this in perspective, a sheet of paper is about 100,000 nanometers thick. At this scale, the properties of materials can differ significantly from their bulk counterparts, leading to unique and often unexpected behaviors.
The Birth of Nanotechnology
Although the term "nanotechnology" was coined by physicist Richard Feynman in 1959, the roots of this field trace back to ancient times when artisans manipulated nanoparticles to create vibrant stained glass. However, it wasn't until the 1980s that scientists gained the tools to work at the nanoscale, heralding the birth of modern nanotechnology.
