Poly(D,L-lactide) (PDLLA) is widely used in the medical field due to its biocompatibility and biodegradability. It is commonly employed in the production of sutures, drug delivery systems, and tissue engineering scaffolds. In sutures, PDLLA provides temporary support during wound healing and gradually degrades, eliminating the need for removal. In drug delivery, it serves as a carrier for controlled release of medications, ensuring sustained therapeutic effects. Additionally, PDLLA is utilized in tissue engineering to create scaffolds that support cell growth and tissue regeneration, eventually breaking down as new tissue forms. Beyond medical applications, PDLLA is used in the cosmetics industry for producing microspheres that enable slow release of active ingredients. It is also applied in packaging to create environmentally friendly, biodegradable materials. Its versatility and safety make it a valuable material in advancing medical treatments, cosmetics, and sustainable technologies.
