Poly(D,L-lactide) (PDLLA) is a biocompatible and biodegradable polymer widely used in the medical field. It is commonly employed in the production of absorbable sutures and wound dressings that dissolve in the body over time, eliminating the need for removal after surgery. PDLLA is also utilized in drug delivery systems, where it acts as a carrier for controlled release of pharmaceuticals, ensuring a steady and prolonged therapeutic effect. In orthopedic applications, it is used to create temporary implants, such as screws, pins, and bone fixation materials, that gradually degrade as the bone heals. Additionally, PDLLA is applied in tissue engineering to fabricate scaffolds that support cell growth and tissue regeneration.

Beyond medicine, PDLLA finds use in cosmetics as injectable fillers for facial contouring and wrinkle reduction. It is also employed in research and development of biomaterials for tissue transplantation. In the food industry, PDLLA serves as a material for biodegradable packaging and coatings, helping to reduce plastic waste.

Its versatility, safety, and natural degradability make PDLLA a valuable material in advancing medical treatments, cosmetic procedures, and sustainable technologies.
