The proposed project concerns the study of liquid flow through nano-scopic channels (Æ = 5-50 nm) the diameter of which can be reversibly modified by external stimuli (e.g. changes in pH, changes in temperature, illumination). The channels will be constructed by self-assembly of block copolymers containing stimulus-responsive blocks. The project comprises the tailormade synthesis of the block copolymers, the formation of membranes with macroscopically aligned nano-pores, and the study of liquid flow through the membranes as a function of the external stimulus. Single molecule fluorescence microscopy ("single molecule tracing") shall be used to locally characterize the flow. Both the stimulus-responsive block copolymers and the membranes will be available to other members of the Schwerpunktsprogramm. The technique of single molecule tracking may as well be of use for other partners in the SPP.

拟议的项目涉及研究液体通过纳米级通道（Æ = 5-50 nm）的流动，其直径可以通过外部刺激（例如pH值的变化，温度的变化，照明的变化）可逆地改变。通道将通过包含刺激响应块的嵌段共聚物的自组装来构建。该项目包括量身定制的嵌段共聚物的合成，具有宏观排列的纳米孔的膜的形成，以及作为外部刺激功能的液体流过膜的研究。单分子荧光显微镜（“单分子示踪”）应使用局部表征流动。刺激响应嵌段共聚物和膜将提供给schwerpunktsprogram的其他成员。单分子跟踪技术也可以用于SPP的其他合作伙伴。
