With reference to carbon nanotubes consider the following statements

Q. With reference to carbon nanotubes consider the following statements

1. they can be used as Carrier 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 following statements given above are correct?

1. 1 and 2 only
2. 2, 3 and 4 only
3. 1, 3 and 4 only
4. 1, 2, 3 and 4

Answer: 1, 2, 3 and 4

A carbon nanotube is an allotrope of carbon that is shaped like a tube of carbon atoms. Carbon nanotubes are very tough and hard to break, but still relatively light. Some are very long. Because of their high strength, carbon nanotubes may one day be used for bulletproof armour and other uses needing hard, lightweight materials. A few carbon nanotubes also let electricity through them. Some may be up to 1,000 times better at conducting electricity than metals like copper and silver.

Application of Carbon Nanotube (CNTs)

Their unique composition, geometry, and properties enable numerous potential carbon nanotubes applications. Getting costs down to commercially viable levels has proven challenging but increasing scale is happening.
