Release studies of naked DNA, polyplexes and lipoplexes from polymeric films

This report details the study done on the stability, release and transfection efficiencies of naked DNA, polyplexes and lipoplexes from different polymeric films in which they were entrapped. The polymeric system studied includes PLGA (53/47), PCL and PEVAC .The release profile was determined by qua...
