Nanotechnology

Nanotechnology is the science of understanding and manipulating materials on a nanometre scale. A nanometer is just one billionth of a metre, or the length of a few atoms placed end-to-end. Already nanotechnology is being used in the production of some microprocessors, batteries, computer displays, paints and cosmetics. But this really is just the begnning of a manufacturing and medical revolution.

The Nanotechnology is defined as the study and use of structures between 1 nanometer and 100 nanometers in size. To give you an idea of how small that is, it would take eight hundred 100 nanometer particles side by side to match the width of a human hair. While this is the most common definition of nanotechnology researchers with various focuses have slightly different definitions.

There are many different points of view about the nanotechnology. These differences start with the definition of nanotechnology. Some define it as any activity that involves manipulating materials between one nanometer and 100 nanometers. However the original definition of nanotechnology involved building machines at the molecular scale and involves the manipulation of materials on an atomic (about two-tenths of a nanometer) scale.
