RESUMO
Studies of DNA complexes with cationic liposomes are prompted by the search for nonviral DNA carriers for gene therapy. Recent experiments have identified a stable multilamellar phase in which ordered smectic layers of DNA alternate with cationic bilayers. In this paper we identify the forces governing DNA adsorption on cationic lamellae, including a membrane-induced attraction between the adsorbed DNA. Calculating the DNA interhelical spacing as a function of system composition, the model successfully explains recent surprising observations.
