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.
