Nanotechnology: Driving India’s Scientific and Technological Progress
UPSC Prelims GS Paper 1 and GS Paper 3 (Science and Technology – Developments and National Missions).
Introduction
Nanotechnology is the science and engineering of materials and devices on a very small scale—one billionth of a meter (nanometer). At this scale, materials often exhibit unique properties compared to their bulk counterparts, enabling revolutionary advances in medicine, energy, agriculture, electronics, and more. Recognizing its transformative potential, India has prioritized nanotechnology development through dedicated missions, institutions, and collaborations.
India’s National Nano Mission
Launched in 2007 by the Department of Science and Technology (DST), the National Nano Mission aims to foster research, innovation, and commercialization of nanotechnologies, positioning India as a global leader in this arena. The mission supports:
- Establishing research centers specializing in nanomaterials, nanoelectronics, and nanosystems
- Strengthening industry-academic linkages and encouraging startups
- Promoting multidisciplinary collaboration and skilled workforce development
- Supporting policies to ensure safe and responsible nanotech development
Key Institutions and Initiatives
- Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru: Pioneer in interdisciplinary nanoscience research since 1989.
- Institute of Nano Science and Technology (INST), Mohali: Focuses on application-oriented nanotech R&D.
- Council of Scientific and Industrial Research (CSIR): Facilitates integration of nano research with industrial development.
- Major IITs and IISc also conduct cutting-edge research in nanotech fields.
Applications of Nanotechnology in India
Healthcare and Medicine
- Targeted drug delivery systems improve treatment effectiveness while minimizing side effects.
- Nanoparticles assist in cancer therapy, diagnostics, and vaccine development (e.g., Bharat Biotech’s Covaxin development using nanotech platforms).
- Nano-based biosensors help in early detection of diseases.
Clean Energy and Environment
- Nanomaterials enhance solar cell efficiency and energy storage devices like batteries and supercapacitors.
- Nano-filters remove pollutants, heavy metals, and microplastics from drinking water, e.g., Tata Chemicals’ nanofiltration device.
- Smart textiles and coatings for reducing environmental impact.
Agriculture
- Nano-fertilizers enhance nutrient delivery and reduce environmental runoff.
- Nano-encapsulated pesticides allow controlled release, minimizing harmful effects.
- Nanotech sensors monitor soil health and crop conditions.
