Poly(D,L-lactide) (PDLLA) is widely used in the biomedical field 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 pharmaceuticals, ensuring sustained and targeted delivery of therapeutic agents. PDLLA is also utilized in the fabrication of surgical sutures, bone fixation devices, and scaffolds for tissue engineering, providing temporary support for cell growth and tissue regeneration. Its ability to degrade into non-toxic byproducts makes it suitable for use in absorbable implants, reducing the need for secondary surgical removal. Additionally, PDLLA is applied in cosmetic and dermatological treatments, such as dermal fillers, where it helps stimulate collagen production and improve skin texture.
