摘　　要：响应性光子晶体(Responsive photonic crystals,RPCs)具有无毒、无标记、低消耗和裸眼可视的优点,pH响应性光子晶体(pH-RPCs)为食品安全、生物医药、水体环境等领域提供了一种简便的检测方式。目前主要发展了胶体粒子组装体/反蛋白石、层状堆叠和全息三种结构类型的pH-RPCs。本文在介绍光子晶体(Photonic crystals,PCs)pH响应原理的基础上,从制备方法、结构特点和pH响应性能(如灵敏度、响应时间、可视化)等方面对上述pH-RPCs进行了详细的综述,分析总结了它们各自的优势和不足,并对其未来的发展进行了展望。Responsive photonic crystals(RPCs)provide a simple,non-toxic,label-free and low-cost approach to the visualized pH detection in the fields of food safety,biological medicine and water protection.The already-developed pH-responsive photonic crystals(pH-RPCs)mainly include three structural types,i.e.colloidal particles assembled structure or inverse opal,layered stacking and holography.This review illustrated the working principle of pH response of photonic crystals(PCs),and subsequently offers elaborate descriptions about the preparation methods,structural features and response performance including sensitivity,response time and readability with respect to the above mentioned pH-RPCs.It ends with a summary of the pH-RPCs’advantages and disadvantages,as well as a rough prospect for the future development trend.
