Degradation study for nonmicrostructured PLGA/gelatin materials at different composition in aqueous solution. (a) Trend of percentage weight loss versus time for PLGA/gelatin samples; (b) change of weight average molecular weight (Mw) as function with time; (c) trend of number average molecular weight (Mn) versus time; (d) polydispersity index (PDI) as function with time.
