9710001本研究的重点是将纳米多孔薄膜作为选择性化学传感器的主体，这些传感器是由包裹在微孔和介孔主体薄膜中的光学响应性受体组成的有序纳米结构组装而成的。这种新颖的结构是通过首先在修饰的传感器衬底上诱导某些分子筛晶体和介孔有序通道结构的生长，然后将受体位置封装到这些通道中来形成的。使用这种方法，可以在光纤上创建化学敏感的纳米结构，这种结构将独特的化学选择性与高稳定性结合在一起，因为封装在坚硬的主机笼子中。本研究的重点是纳米多孔膜作为选择性化学传感器的主体，这些传感器是由包裹在微孔和介孔主体薄膜中的光学响应性受体组成的有序纳米结构组装而成的。这种新颖的结构是通过首先在修饰的传感器衬底上诱导某些分子筛晶体和介孔有序通道结构的生长，然后将受体位置封装到这些通道中来形成的。使用这种方法，可以在光纤上创建化学敏感的纳米结构，这种结构将独特的化学选择性与高稳定性结合在一起，因为封装在坚硬的主机笼子中。***

9710001 Bein The focus of this research is on nanoporous films as hosts for selective chemical sensors derived from assembled ordered nanostructures composed of optically responsive receptors encapsulated in thin films of micro- and mesoporous hosts. The novel structures will be formed by first inducing the growth of certain molecular sieve crystals and mesoporous ordered channel structures on modified sensor substrates, followed by encapsulation of receptor sites into these channels. Using this approach, it will be possible to create chemically sensitive nanostructures on optical fibers that combine unique chemical selectivity with high stability due to encapsulation in rigid host cages. %%% The focus of this research is on nanoporous films as hosts for selective chemical sensors derived from assembled ordered nanostructures composed of optically responsive receptors encapsulated in thin films of micro- and mesoporous hosts.
