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?
1 and 2 only
2, 3 and 4 only
1, 3 and 4 only
1, 2, 3 and 4
Solution
Carbon nanotubes are used as drug/antigen carriers, can serve as artificial blood capillaries (e.g., MWCNT-PU vascular grafts), are used in biosensors, and microbes including bacteria and fungi can degrade them — hence biodegradable. All four statements correct. Answer: (d).
