Explanation:
1. Carbon nanotubes can be used as carriers of drugs and antigens in the human body. They have a high surface area and can be functionalized to deliver therapeutic agents.
2. While carbon nanotubes have been explored for various biomedical applications, such as tissue engineering, they are not typically used as artificial blood capillaries.
3. Carbon nanotubes can indeed be used in biochemical sensors due to their unique electrical and optical properties. They can detect and interact with specific molecules, making them useful for sensing applications.
4. Carbon nanotubes are not biodegradable. They are known for their high stability and durability, which can be advantageous in some applications but can also raise concerns about their environmental impact and long-term effects.
