Is Nano a No-No? Nanotechnology Advances into Buildings

Nanotechnology is an applied science working with materials at the scale of 1 to 100 nanometers, with a nanometer being a billionth of a meter. Everything is composed of atoms and molecules that are measured at the nanoscale and smaller, but only since the 1980s have scientists been able to see and manipulate matter at that scale, allowing them to precisely engineer materials for special properties. Products using nanotechnology take advantage of the special properties of nanoscale particles, or nanoparticles. Most...
