Nano science refers to the science & discipline and nanotechnology refers the
applied part of it including the engineering to control, manipulate and structure
the matter at an unimaginably small scale: nano scale. This scale is also referred
to as ‘atomic’ or ‘molecular’ scale which is 100 nanometers
or smaller. This capability also simultaneously gives us the ability to build materials
and devices or shapes and products on that scale. Because of the brevity in operation,
smarter and lighter products can be made from the molecules of the same matter with
every atom in its specified place through ‘positioned assembly’ or ‘self
assembly’. The matter displays unimaginably different qualities when manipulated
and structured at nano scale.
