Coordination of the French/German collaborative research group "Complex Fluids: From 3 to 2 Dimensions"

磷脂与聚电解质和糖苷聚合物的相互作用，两者都是生物起源，应研究层状系统。对于两亲分子单层，用x射线衍射和傅里叶红外光谱研究了膜中脂质排列的结构。聚合物的排列应通过椭偏、x射线和中子反射率进行研究。用FTIR和NMR对囊泡和包覆胶体的耦合进行研究。光漂白后的荧光恢复将研究脂质的横向扩散。核磁共振技术还将用于研究膜的膨胀和膜中水的比例，以及膜和脂质头基团之间的差异。特别感兴趣的将是耦合和动力学之间的关系，聚电解质和糖苷聚合物的so1/gel跃迁及其对调制或配体结合的重要性。总的来说，该项目旨在了解耦合脂质/聚合物系统的结构和动力学之间的关系及其与生物物理和化学的相关性。

The interaction of phospholipids with polyelectrolytes and glycosidic polymers, both of biological origin, shall be investigated for layered systems. For amphiphile monolayers structural studies which concern the lipid arrangement in monolayers is studied by X-ray diffraction and FTIR spectroscopy. The polymer arrangement shall be investigated by ellipsometry, X-ray and Neutron reflectivity. The coupling shall be studied by FTIR and NMR spectroscopy with vesicles and coated colloids. Lateral diffusion of lipids will be investigated by fluorescence recovery after photobleaching. NMR techniques will also be employed to investigate the swelling of films and the fraction of water in the film as well a between film and lipid head groups. Of special interest will be the relation between coupling and dynamics, so1/gel transitions of polyelectrolytes and glycosidic polymers and their importance for modulation or ligand binding. Altogether the project aims at understanding the relation between structure and dynamics in coupled lipid/polymer systems and its relevance for biophysics and -chemistry.
