Poly(D,L-lactide) (PDLLA) is widely used in the medical and pharmaceutical industries due to its biocompatibility and biodegradability. It is commonly employed in the development of drug delivery systems, where it serves as a carrier for controlled release of medications, ensuring sustained and targeted therapeutic effects. PDLLA is also utilized in the fabrication of surgical sutures, implants, and scaffolds for tissue engineering, as it gradually degrades in the body without causing adverse reactions. Its ability to be molded into various forms makes it suitable for creating custom medical devices. Additionally, PDLLA is used in cosmetic and dermatological applications, such as dermal fillers, where it promotes collagen production and skin rejuvenation. Its versatility and safety profile make it a valuable material in advancing healthcare technologies.
