The 5-Second Trick For sustained release and prolonged release

At pH 2, the elevated permeability in the polyelectrolytes film facilitates the incorporation of DOX Within the PSS/PAH multilayers. Then the adjustment of pH at 8 will cause the contraction from the polyelectrolytes along with the drug molecule becomes trapped In the polyelectrolyte film. The subsequent washing will clear away any nontrapped DOX m
