Question

With reference to the carbon nanotubes, consider the following statements:
1. They can be used as the carriers of drugs and antigens in the human body.
2. They can be made into artificial blood capillaries for an injured part of the human body.
3. They can be used in biochemical sensors.
4. Carbon nanotubes are biodegradable.
Which of the statements given above are correct?

Accepted Answer

Carbon nanotubes' unique electrical and mechanical properties make them suitable for drug delivery systems and as components in biochemical sensors. They can be functionalized to target specific cells or tissues. While research is ongoing for biocompatibility and potential applications like artificial capillaries, their complete biodegradability in the human body is still a subject of active investigation and not a universally established fact, unlike their utility in drug delivery and sensors.
