    • The results for the present system (cationic CPE and anionic liposomes) are quite different from those reported in a recent study of an anionic CPE with liposomes formed from a zwitterionic phospholipid (ref 35.). In this study, it is indicated that the CPE may associate with the surface of the liposome or become entrapped within the liposome, there is very little crossing of the bilayer by the polymer

    • note
    • A reviewer has suggested that the results observed in this study may be explained by an alternative possibility that the polymer-liposome interaction may lead to formation of a cylindrical structure where the polymer is "wrapped" by a coat of phospholipid. We concur with the reviewer that this could explain the observed results and are planning experiments to test this possibility. On the other hand, foramtion of such cylindrical structure would probably lead to film collapse or contraction when the polymer is added to phospholipid monolayer at the air/ water interface and this is not observed in section 3.4.3 where the results from monolayer insertion experiments are described.
