The roots of the word “nano” is traced to the Greek word “Nanos”, which means dwarf or midget and used to refer the materials technology that operates in a miniature scale. Nanotechnology is the manipulation of matter at least one dimension sized from 1 to 1oo nm. Accordingly, nanoscience is the study of the fundamental principles of matter that at least in one dimension ranged between 1 to 100 nm. One nano-meter is one billionth of a meter or 1/1000000000 m.
