Nanotechnology is more than just a field of science, it can be regarded as an extension of to applied science fields. It is multidisciplinary, similar to realization of Quantum physics and Classical Physics, the properties of a nano-sized materials with non-nano-sized materials differs greatly and significantly most of the times.

Take for an example, solid silicon (Si) with greyish, dull, boring look has nothing fascinating to see by its outward appearance. However, if one would filter it out with nano-sized filter scoop, a variety of colours will occur. A change of physical appearance will occur according to the video embedded.
