With reference to carbon nanotubes, consider the following statements : 1. They can be used as carriers of drugs and antigens in the human body. 2. They can be made into artificial blood capillaries for an injured part of human body. 3. They can be used in biochemical sensors. 4. Carbon nanotubes are biodegradable. Which of the statements given above are correct ?
A
1 and 2 only
B
2, 3 and 4 only
C
1, 3 and 4 only
D
1, 2, 3 and 4
Correct Answer
Explanation
Option (D) is correct because carbon nanotubes (CNTs) possess unique mechanical and electrical properties that allow them to serve as drug carriers, tissue scaffolds for artificial capillaries, and sensitive biosensors. While often perceived as inert, functional
