At pH 2, the greater permeability from the polyelectrolytes movie facilitates the incorporation of DOX inside the PSS/PAH multilayers. Then the adjustment of pH at eight results in the contraction of your polyelectrolytes and also the drug molecule becomes trapped inside the polyelectrolyte film. The subsequent washing will eliminate any nontrapped
