While Nanotechnology professionals are in great demand in mainstream electronics, industrial products and healthcare markets. Nanotechnology is still in early stages of development in India. The Government of India has instituted S&T Initiatives in Nanotechnology. However, Nanotechnology graduates have plenty of opportunities in medical, healthcare industry research, environment industries, pharmaceutical, agriculture, universities, private research institutes, educational institutes, entrepreneurial, investment advisors in biotechnology, research and development in government, product development and advising, communication and media and interfacing of new technologies.
I would suggest you to choose nanotechnology.
