Nanotechnology refers to the projected ability to construct items from the bottom-up, using techniques and tools being developed today to make complete, high performance and a high quality products. It is the study of manipulating matter on an atomic and molecular scale. It deals with the structure sized between 1-100 nanometer in at least one dimension. Imagine how nanotechnology works in the name of measurement and size for because one nanometer (nm) is one billionth of a meter. To put that scale in another context , the comparative size of a nanometer to meter is the same as that of a marble to the size of the Earth. Another way of putting it: a nanometer is the amount an average man’s bread grows in the time it takes him to raise the razer to his face.
