Nanotechnology – Science and Technology Current Affairs Notes (May 2025) for BPSC & UPSC
आइए आसान भाषा में समझते हैं कि Nanotechnology क्या है, इसकी latest developments क्या हैं, और क्यों ये UPSC और BPSC के लिए important topic है।
📌 Nanotechnology क्या है?
Nanotechnology एक ऐसी technology है जिसमें पदार्थों (materials) को nanoscale (1 nanometer = 10⁻⁹ meter) पर control और manipulate किया जाता है।
➡ Means: किसी भी चीज़ को बहुत छोटे atomic या molecular level पर control करना।
➡ Example: Gold nanoparticles को drug delivery में use करना।
💡 Why Nanotechnology is Important for Exams?
- UPSC और BPSC में Science & Tech के section में अक्सर इससे related सवाल आते हैं।
- Current affairs में अगर कोई नई nano-technology आई है या भारत में कोई नया प्रोजेक्ट शुरू हुआ है, तो वह exam में पूछा जा सकता है।
🧪 Latest Developments in Nanotechnology (May 2025)
1. भारत में पहला Nano-Medicine Manufacturing Hub लॉन्च
- Location: Hyderabad
- Highlights: इस hub में cancer, tuberculosis और neurological diseases के लिए targeted nano-drugs बनाए जा रहे हैं।
- यह project Make in India के तहत promote किया गया है।
2. ISRO ने लॉन्च किया Nano-Satellite Testing Facility
- इस facility में specially nano-satellites को test करने के लिए advanced tools लगाए गए हैं।
- Small satellites missions के लिए ये बहुत जरूरी step है।
3. IIT Bombay द्वारा “Nano-Solar Paint” विकसित
- एक ऐसी paint जो sunlight से electricity बना सकती है।
- इसे घरों की छत पर लगाया जा सकता है, जिससे renewable energy को boost मिलेगा।
4. Nanotechnology in Agriculture
- ICAR (Indian Council of Agricultural Research) ने nano-fertilizers को promote करना शुरू किया है।
- इससे कम मात्रा में fertilizer use करके ज्यादा production possible है।
5. Nano Biosensors for Disease Detection
- ICMR ने एक portable device लॉन्च किया है जो nano-sensors की मदद से diseases को early stage पर detect कर सकता है।
- इसका use rural health care में किया जाएगा।
