基于虹膜状纳米阀原理的响应纳米孔膜材料

Stimuli responsive pores towards gated membranes based on iris-like nano-valves

该项目旨在开发一种纳米孔入口处具有可控闸口的膜。刺激响应材料将嫁接在孔表面上，作为充当纳米阀以促进孔的收缩或扩张；通过膜表面上吸附化合物生物传感反馈进行选择性扩散。该项目将集中在虹膜形状的聚合物的设计上，该聚合物能够基于特定的光或电刺激打开/关闭。仿生虹膜将基于来自在膜表面内实现的传感单元的反馈进行选择性扩散。光响应和电响应聚合物的最新设计及其集成为实现复杂的3D结构材料铺平了道路。

该项目将解决：
（i）响应性聚合物的虹膜设计和形成，
（ii）在膜表面上实施生物传感器和
（iii）纳米阀的反应性。

这一材料将主要应用在分析化学和高选择性膜，超低含量污染物的去除、质量控制和系统保护、以及先进的纳米流体；新型有效的分离系统在其它众多领域中也有广泛的前景。

This project aims at developing membranes with controllable gate-keepers at the site of the entrance of the pores. Stimuli responsive materials will be anchored and grafted across the surface of the pores to facilitate the constriction or expansion of the pores and thus act as nano-valves, allowing for selective diffusion based on bio-sensors feedback for adsorbed compounds strategically across the surface of the membranes. The strategy will be focused on the design of iris shaped polymers able to open/shut based on specific light or electrical stimuli. The iris, bio-mimicking an eye iris, will allow for selective diffusion based on the feedback from the sensing unit implemented within the membrane surface. The recent design of light- and electrically responsive polymers and their integration has paved the way for the implementation into complex 3D architectures and will be utilized as a base for this project.
The project will tackle fundamental challenges related to:
(i)        the iris design and shape etching from responsive polymers,
(ii)        the implementation of biosensors across the surface of membranes and
(iii)        the reactivity of the nano-valve.

The potential of such an approach will be primarily in analytical chemistry and highly selective membranes and find applications in ultralow trace contaminant removal, quality control and system protection and advanced nano-fluidics. The applications will span beyond the sole scope of the application tested in analytical chemistry, drug delivery and in bio-security where selectivity is prime to performance. The opportunities to develop more efficient separation systems will stem from this approach and be useful in a myriad of fields.
