Nanotechnology

Nanotechnology is the science and engineering in the creation of materials, functional structures, as well as nanometer-scale devices. In scientific terminology, nano means 10-9 (0.000000001). One nanometer is like a thousand micrometers, or like a million millimeters, or like a billion feet. In comparison, human hair has a diameter of 50,000 to 100,000 nm, so a nanometer is approximately equal to a hair cut one hundred thousand.
