What is Nanotechnology?
Nanotechnology is the
engineering and manipulation of
materials at the nanoscale, which is typically between 1 and 100 nanometers. It involves various techniques to create structures, devices, and systems with novel properties and functions due to their small size.
How Does Nanotechnology Work?
Nanotechnology works by controlling matter at the atomic and molecular levels. This control is achieved through
nanofabrication techniques such as lithography, self-assembly, and molecular beam epitaxy. By rearranging atoms and molecules, scientists can create materials with enhanced properties like increased strength, lighter weight, or better electrical conductivity.
