Abstract

该文将光子晶体与分子印迹技术结合,制备了分子印迹光子晶体水凝胶膜(MIPHs)作为光学传感器,用于样品中三聚氰胺的快速识别检测。以三聚氰胺为模板分子,通过垂直沉降自组装、填充聚合、去除模板3个步骤,制备得到了反蛋白石结构的三聚氰胺MIPHs。扫描电子显微镜的形貌表征表明,MIPHs具有高度有序的三维大孔结构。该MIPHs作为光学传感器可以将三聚氰胺的分子特异识别过程转换成光学信号,在对目标分析物分析时具有选择性高、响应快、灵敏度高的优点。此外,可以根据MIPHs的颜色变化利用图像软件分析或裸眼识别的方式实现目标分析物快速识别。实验结果表明,在最优条件下,三聚氰胺浓度为10-11~10-6mol/L时,MIPHs的布拉格衍射峰位移从563 nm红移到608 nm,而对三聚氰胺的结构类似物没有明显响应。.
