💡 Analysis & Explanation
Medical Delivery ▼
Nanotubes are highly effective as microscopic delivery vehicles for targeted drug and antigen administration within the human body. Statement 1 is correct.
Sensory Applications ▼
Due to their high electrical conductivity and extreme structural sensitivity, they are widely used in the construction of advanced biosensors. Statement 3 is correct.
Biodegradability ▼
Recent scientific studies have demonstrated that certain functionalized carbon nanotubes can be enzymatically degraded by microorganisms or human cellular enzymes, proving they can be biodegradable. Statement 4 is correct.
Capillary Construction Limitations ▼
While they can be used for tissue engineering scaffolds, directly forming functional "artificial blood capillaries" out of pure carbon nanotubes for human injury replacement is not a standard or clinically viable medical practice, rendering statement 2 scientifically inaccurate in this context.
Conclusion ▼
Statements 1, 3, and 4 accurately reflect the verified applications of carbon nanotubes.
