Pranab Ghosh interviews BR Mehta, professor of nanotechnology, department of physics, IIT-Delhi.
Please trace the evolution of the study of nanotechnology in India?
Most of the research on nanoscience in India started about seven to eight years back. The major impetus to the research came from the Nano-mission programme of the Department of Science and Technology, Government of India.
What is the scope of work of a nanotechnologist in India as well as abroad?
In India, nanotechnology can be used to address important problems and issues related to health, water, energy and environment. Low-cost sensors can be developed for the early detection, diagnosis of diseases. Drug delivery to carry out site-specific treatment of different ailments can be carried out using nanoparticle-drug composites. Purification of water can be carried out using nanocomposite filter materials. Nanostructured solar cell and fuel cells can be used for efficient and low cost energy conversion.
Are there adequate numbers of skilled nanotechnologists in the country today? If not, why?
With the launch of various Government of India programmes, the number of researchers in nanoscience and nanotechnology is increasing. More efforts are required to increase the number of specialists in this area.
What are the challenges facing the profession of nanotechnology today?
Integration of nanodevices with micro and macro scale devices is one of the major challenges for converting labscale research to ready-to-use devices. Drug delivery for directing low doses of drugs to specific points in the body, low cost nanostructured devices for producing energy are going to be the major developments.
Who are the leading employers in India and globally?
Research laboratories, chemical, pharmaceutical, polymer, rubber and energy companies are the leading employers.
