摘要：
DNA shows strong interactions with cationic cosolutes and these have both biological and technological significance. We outline our research on various mixed systems of DNA and cationic amphiphiles including the interaction of DNA with simple cationic surfactants as well as the interaction with catanionic mixtures and positively charged catanionic vesicles. An overview from phase behavior to microstructure will be presented. We will also address DNA compaction and decompaction phenomena in different systems. Finally, simulations on DNA confinement and interaction with cationic polyions are considered. (C) 2003 Published by Elsevier B.V.
