Biotechnology in India: Applications & UPSC Notes
Biotechnology is the use of living organisms, biological systems, and cellular processes to develop products, technologies, and solutions for human benefit. India’s biotech sector has grown to over $130 billion (2024-25 estimates), making it among the top 12 biotech destinations globally. The Department of Biotechnology (DBT) under the Ministry of Science and Technology drives policy, while institutions like ICGEB, NBRC, and NCBS lead research. For UPSC, biotechnology is a recurring Science and Technology topic in both Prelims and Mains (GS Paper III).

Gene Therapy and Gene Editing
- CRISPR-Cas9: Revolutionary gene-editing tool — Indian researchers are working on sickle cell disease, thalassemia, and crop improvement applications
- Gene therapy trials: AIIMS and other institutions conducting clinical trials for genetic disorders

- Point-of-care diagnostics: Low-cost biotech diagnostic kits for TB, malaria, and dengue
Industrial and Environmental Biotechnology
Biofuels
- Ethanol Blending Programme: Target of 20% ethanol blending in petrol (E20) by 2025-26
- Second-generation (2G) ethanol: Producing ethanol from agricultural waste (rice straw, bagasse)
