Dynamics of Micro/Nano-Structure Formation in Quasi Two-Dimensional Fluids: Applications in Directed Biomaterial Transport

该研究项目旨在控制超薄膜(厚度为nm量级的准二维薄膜)中耗散微纳米结构的形成，并将其应用于流体通道。在项目的第一部分，我们将重点研究耗散结构形成的动力学，例如(1)聚合物/表面活性物质薄膜中的粘性手指和孔洞，(2)脂/脂聚合物单分子膜中的“微/纳米通道”。三相接触线附近局部厚度分布的动态变化将通过(原位)成像椭偏仪进行监测。在第二部分中，我们将探索这种结构在微流体中的技术应用。在这里，我们的目标是定位膜蛋白在“自组装的流体通道”的定向运输。

The proposed research project aims at control of dissipative micro-to-nanostructure formation in ultrathin films (quasi two-dimensional films with thickness of nm order), and their application as fluidic channels. In the first part of the project, we will focus on the dynamics of dissipative structure formation, such as (1) viscous fingers and holes in polymer/surfactant films, and (2) "micro/nano-channels" in lipid/lipopolymer monolayers. Dynamic changes in the local thickness profile in the vicinity of the three phase contact line will be monitored by (in-situ) imaging ellipsometry. In the second part, we will explore the technological application of such structures in micro-fluidics. Here, we target the localization of membrane proteins in "self-assembled fluidic channels" for the directed transport.
