Release kinetics of ZOL from PEC films. The relative ZOL content for PEC-0.9 (a) and PEC-1.1 (b) systems of ZOL/CS/PEI-M-25 K-1:5 (cubes), ZOL/CS/PEI-25 K-1:5 (triangles) and ZOL/CS/PEI-750 K-1:5 (circles) samples is plotted versus exposure time (0, 5, 30, 60, 120, 1200 min) to the release medium (0.1 mg/ml PBS). For comparison the kinetic curve for a pure ZOL film (black) is shown.
