कार्बन नैनोट्यूबों के संदर्भ में, निम्नलिखित कथनों पर विचार कीजिए :
1. इनको मानव शरीर में औषधियों और प्रतिजनों के वाहकों के रूप में प्रयुक्त किया जा सकता है ।
2. इनको मानव शरीर के क्षतिग्रस्त भाग के लिए कृत्रिम रक्त केशिकाओं के रूप में बनाया जा सकता है ।
3. इनका जैव-रासायनिक संवेदकों में उपयोग किया जा सकता है ।
4. कार्बन नैनोट्यूब जैव-निम्नीकरणीय (biodegradable) होती हैं ।
उपर्युक्त कथनों में से कौन-से सही हैं ?
सही उत्तर (C) (c) 1, 3 and 4 only है।
व्याख्या:
Statement 1 is correct: In case of Cancer, CNTs as drug delivery vehicles (carriers) have shown potential in targeting specific cancer cells with a dosage lower than conventional drugs used. Statement 2 is correct: CNTs have been successfully applied in pharmacy and medicine due to their high surface area that is capable of adsorbing or conjugating with a wide variety of therapeutic and diagnostic agents. Hence, they can be made into artificial blood capillaries for an injured part of the human body. Statement 3 is correct: New materials CNTs are promising building blocks for biosensors due to their unique electronic and optical properties. Statement 4 is correct: Microbes including bacteria and fungi have the ability to degrade carbon nanotubes (CNTs), graphene (GRA), and their derivatives.
In English (Question & Model Answer)
