Stereocomplex poly(lactide)s (sc-PLAs) were obtained from solution blending of 3-armed poly(L-lactide) (3PLLA) and linear poly(D-lactide) (PDLA) and between enantiomeric 3PLAs. Differential scanning calorimetry and wide-angle X-ray diffraction results indicated that racemic crystallites were preferentially produced in all the binary blends.

Bioresorbable polylactides are one of the most important materials for tissue engineering applications. In this work we have prepared scaffolds based on the two optically pure stereoisomers: poly(L: -lactide) (PLLA) and poly(D: -lactide) (PDLA). The crystalline structure and morphology were

Microparticulate systems for delivery of therapeutics to DCs for immunotherapy have gained attention recently. However, reports addressing the optimization of DC-targeting microparticle delivery systems are limited, particularly for cases where the goal is to deliver payload to DCs in a

The effects of the addition of poly(D-lactide) (PDLA) on the crystallization behavior of poly(L-lactide)(PLLA) were investigated by means of differential scanning calorimetry (DSC) and temperature-dependent X-ray diffraction(XRD). When the blends were cooled from different temperatures (250, 240, and 190 °C)
