分子印迹光子晶体的研究进展EI北大核心CSCD

光子晶体是至少两种不同折射率介质周期性排列而成的有序结构材料,通过改变其平均折射率或晶格间距等参数可以实现对光的调控。响应性光子晶体结构与分子印迹技术相结合制备的分子印迹光子晶体化学传感器因特异性强、灵敏度高且具有自表达能力等优点而受到人们的青睐,为微量及痕量物质的检测提供了新思路。本文着重介绍了基于二维和三维光子晶体的传感材料,尤其是分子印迹光子晶体(MIPC)的制备方法、性能特点和应用研究进展,对分子印迹光子晶体在可视化检测的研究前景做了展望,对提高分辨率、稳定性等问题做了分析。

Progress in molecular imprinted photonic crystals

Photonic crystal is a kind of ordered material which consists of two or more periodic arranged refractive index materials, and the propagation of light can be controlled by changing its average refractive index or lattice spacing. The molecularly imprinted photonic crystal chemical sensors based on the combination of responsive photonic crystal structure and molecular imprinting technique have attracted research interests due to their strong specificity, high sensitivity and self-expression ability, which also provide a novel strategy for the trace detection. In this review, the two-and three-dimensional photonic crystal sensor materials were introduced, and the preparation, properties and applications of molecular imprinted photonic crystal(MIPC) were reviewed. The future research focus such as the improvement of resolution and repeatability of MIPC visual detection materials was analyzed and prospected at last.
