Definition
Nanotechnology is the manipulation of matter on an atomic and molecular scale. Think of it as building things from the tiniest building blocks imaginable. It involves working with materials that are only a few nanometers in size (a nanometer is one billionth of a meter). It has the potential to revolutionize many fields, including medicine, electronics, and energy. It's more than just making things small; it's about creating new properties and functionalities. Nanotechnology is a frontier of science and engineering.
