Biodegradable films were prepared by casting acetone solutions of mixtures of a high molecular weight PO~Y(DLlactic acid) (HMW-PLA50) with 0, 10, and 30% wlw poly(DL-lactic acid) oligomers (LMW-PLA50), before drying. From size exclusion chromatography (SEC) it was shown that degradation occurred dur
This study was designed to investigate the in vitro degradation of thin poly(DL-lactic-co-glycolic acid) (PLGA) films for applications in retinal pigment epithelium transplantation and guided tissue regeneration. PLGA films of copolymer ratios of 75:25 and 50:50 were manufactured with thickness leve
