利用一种新的生物相容性聚合物——氨基功能化聚（epsilon-己内酯）（PCL-NH2）对多孔硅基一维光子晶体（如Bragg镜和光学微腔）进行了修饰，并将其表征为光学生化传感器。包裹的聚合物在暴露于碱性溶液时增加了纳米晶体基质的强化学稳定性，保持了设备监测挥发性物质和化合物的传感能力。基于这些结果，这些杂化结构可以作为生化应用的高性能平台。(C) 2009年美国物理研究所。(DOI: 10.1063/1.3177344)
Porous silicon based one-dimensional photonic crystals, such as Bragg mirror and optical microcavity, has been modified by infiltration of a new biocompatible polymer, an amino functionalized poly(epsilon-caprolactone) (PCL-NH2), and characterized as optical biochemical sensors. The entrapped polymer adds strong chemical stability to the nanocrystalline matrix on exposure to alkaline solutions preserving the device sensing abilities in monitoring volatile substances and chemical compounds. On the basis of these results, these hybrid structures can be proposed as a high performance platform for biochemical applications. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3177344]
