The fusion of technology with knowledge creates what the world once assumed as miracles and biotechnology can be considered as a perfect example where the knowledge of biology when blended with technology is making the world a better place by enhancing the quality of life and alleviating the human sufferings. ‘Biotechnology’, the term was coined by a Hungarian engineer, Karl Ereky and is defined as per the UN convention on biological diversity as, “Any technological application that uses biological system or living organisms to make or modify the process or products for specific use.”  Biotechnology has touched almost every aspect of human life and has carved its niche too. Biotechnology dealing with medical and health care is termed as Red biotechnology.

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. It is the engineering and technology conducted at ‘Nano’ scale.
