Nanoscience is the study and understanding of matter at ‘Nano-scale’, where unique properties allow never imagined applications and Nanotechnology is the way for manifestation of such novel applications. In other words, Nanotechnology is precise manipulation, control and use of matter at nano scale for design, characterization, and production for different applications, phenomenon or for specific technology.
