Abstract: Two different PLGA samples (Resomer 502 and Resomer 506), either alone or in combinations, were used to prepare microcapsules. Microcapsules were prepared using a double emulsion solvent evaporation technique. The efficiency of encapsulation increased significantly when a mixture of 1 part Resomer 506 and 7 parts Resomer 502 was used to prepare the microcapsules. The efficiency of encapsulation of this batch was 23.7%, whereas the efficiency of encapsulations was only 13.9 and 9.8%, respectively, when the micr…
