Question

The biomedical applications of polyphosphazene polymers are: (A) As structural materials for the construction of heart valves and blood vessels.
(B) They are used in drug delivery systems.
(C) Biodegradable support for in vivo bone regeneration.

• A. (A) and (B) only
• B. (B) and (C) only
• C. (A), (B) and (C)
• D. (A) and (C) only

Hint:

Polyphosphazene polymers have a wide range of biomedical applications due to their biodegradability, making them useful for structural, drug delivery, and regenerative purposes.

Answer 1

The Correct Option is C

Step 1: Understanding Polyphosphazene Polymers.
Polyphosphazene polymers are a class of materials that have a wide range of biomedical applications due to their unique properties such as biodegradability, biocompatibility, and versatility in structural and functional modifications.

Step 2: Analyzing the Options.
- (A) Polyphosphazene polymers are used as structural materials in biomedical applications, particularly for heart valves and blood vessels due to their flexibility and strength. - (B) Polyphosphazene polymers are also used in drug delivery systems, where their biodegradability allows controlled drug release. - (C) These polymers can be used as biodegradable supports for in vivo bone regeneration, as they can be gradually resorbed by the body while providing mechanical support.

Step 3: Conclusion.
Thus, all of the listed applications (A), (B), and (C) are true for polyphosphazene polymers, so the correct answer is option (3).
