logy? Р Nano, es from the Greek word for dwarf. One nanometre is a billionth of a metre. Definitions of ‘nanotechnology’ vary, but it generally refers to understanding and manipulation of matter on the nanoscale, say, from 0.1 run to 100 nm. The significance and importance of controlling matter at the nanoscale is that at this scale different laws of e into play (quantum physics); There are two ways to approach the nanoscale: shrinking from the top down, or growing from the bottom up. The ‘top down’ approach entails reducing the size of the smallest structures towards the nanoscale by machining and etching techniques, whereas the ‘bottom up’ approach, often referred to as molecular nanotechnology, implies controlled or directed self-assembly of atoms and molecules to create structures [3].
