项目摘要

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.

小行星9710001 本研究的重点是纳米多孔膜作为主机的选择性化学传感器来自组装有序的纳米结构组成的光学响应受体封装在薄膜的微米和介孔主机。新的结构将通过首先诱导某些分子筛晶体和介孔有序通道结构在改性传感器基板上的生长，然后将受体位点封装到这些通道中来形成。使用这种方法，将有可能在光纤上产生化学敏感的纳米结构，该纳米结构由于封装在刚性宿主笼中而将联合收割机独特的化学选择性与高稳定性相结合。本研究的重点是纳米多孔膜作为主机的选择性化学传感器来自组装有序的纳米结构组成的光学响应受体封装在薄膜中的微型和介孔主机。新的结构将通过首先诱导某些分子筛晶体和介孔有序通道结构在改性传感器基板上的生长，然后将受体位点封装到这些通道中来形成。使用这种方法，将有可能在光纤上产生化学敏感的纳米结构，该纳米结构由于封装在刚性宿主笼中而将联合收割机独特的化学选择性与高稳定性相结合。 ***
