Poly(D-lactide) (PDLA), a polymer of a stereospecific cyclic di-ester of lactic acid, is used in biomaterial research for the development of devices such as therapeutic drug delivery vessels. Poly(D-lactide) is used for the preparation of microparticles and resorbable polylactide scaffolds.
By poly (D-lactide） made products biological compatibility is good, after the in vivo degradation product by the metabolism out of the body, no harmful and toxic side effects on the human body.

Poly D-lactide is a bioabsorbable and degradable material. Poly D-lactide can be used in medical fields, such as disposable infusion devices, non-removable surgical sutures; controlled release and slow release packaging agents; tissue engineering scaffolds, bone fixation and bone repair materials, microcapsules for injection, microspheres, implant And animal organs support elastomers and other materials.
At present, it is widely used in the fields of medicine, such as disposable infusion apparatus, free disassembly type suture; drug controlled release, sustained release agent packaging; scaffolds for tissue engineering, bone fixation and bone repairing material, injection with of microcapsules and microspheres, implants and animal organs elastomer material support.
