仿生结构一维光子晶体传感器的制备与应用

摘要

Some biological creatures like butterfly wings,beetle and abalone shells have the one dimensional pho-tonic crystal structural color structure.People imitate these one-dimensional photonic crystals to prepare pho-tonic crystal sensors.In this paper,not only the methods of preparing biomimetic structural one-dimensional photonic crystal sensors,such as spin coating method,surfactant self-assembly method,block copolymer self-assembly method and holography method were introduced,but also the usages of determinating temperature, pressure,organic solvent,pH and small chemical or biological molecules.Advantages of this kind of sensors are the convenient preparation,better sensitivity and excellent selectivity.At present,simulation of one-dimension-al biological structure color by more novel preparation methods in theory and more wide applications are re-search hotspots of this photonic crystal sensor field.%很多生物像蝴蝶、甲壳虫、鲍鱼壳等具有一维光子晶体结构色,人们模仿这些一维光子晶体制备了光子晶体传感器.综述了使用旋涂法、表面活性剂自组装法、嵌段共聚物自组装法以及全息法等有效方法制备仿生结构一维光子晶体传感器,并将此传感器应用于温度、压力、有机溶剂、酸度以及化学小分子等多方面的检测.该类传感器优点在于制备方便快速,具有较好的灵敏度和选择性.目前研究方向是采用更多的制备方法模拟一维生物结构色,并在更广泛领域得到广泛应用.
