Used in biomedical applications, particularly in drug delivery systems due to its biocompatibility and biodegradability. Its helical structure allows for stable nanoparticle formation, making it suitable for encapsulating therapeutic agents. Employed in tissue engineering as a scaffold material because it supports cell adhesion and growth. Also explored in controlled release formulations where the ester side chains can be tailored for specific degradation rates. Its optical activity and structural similarity to natural polypeptides enhance its interaction with biological systems.
