Nanotechnology is the science of manipulation of matter on an atomic, molecular, and supramolecular scale. Size of matter varies from 1 to 100 nanometers. Nanotechnology uses fields of science such as surface science,organic chemistry, molecular biology, semiconductor physics, microfabrication, etc. Today engineers are finding a variety of ways to make materials at the nanoscale to take advantage of their advanced features such as higher strength, lighter weight, increased control of light spectrum, and greater chemical re-activity. Nanotechnology finds its application in sunscreens and cosmetics, surface coatings, paints and outdoor furniture varnishes; and cerium oxide as a fuel catalyst. It allows the tennis balls to last longer, golf balls to fly straighter, and even bowling balls to become more durable and have a harder surface, Trousers and socks to last longer and keep people cool in the summer.
