结合溶胶凝胶固定酶的方法和介质膜金属空芯光纤,提出了一种新型空芯光纤结构的化学发光传感腔。研究了将溶胶凝胶敏感膜镀制在空芯光纤内壁的工艺,并对此种新型传感器件的发光和导光模式进行了仿真计算,讨论了传感腔各项参数的优化。设计和搭建了基于新型空芯光纤化学发光腔的传感系统,对隐形眼镜液中双氧水含量的实际测量表明,系统具有较高的检测灵敏度(10 μM)和良好的重复性。传感系统操作简单、响应快速、可小型化,在生化研究、环境监测以及食品工业等领域有广阔的应用前景。
Abstract
A new kind of chemiluminometric sensing cell based on hollow fiber is proposed by combining sol-gel enzyme immobilization and dielectric-coated metallic hollow fiber. The fabrication techniques for coating sol-gel sensing membrane inside the hollow fiber are studied. Transmission mode and luminescence mode of the new device are simulated, and optimization of system parameters is discussed according to the calculation results. A hollow fiber based sensing system is designed and established for detecting hydrogen peroxide concentration. And it is applied to detect the hydrogen peroxide concentration in contact-lens disinfectant solution. A high sensitivity (10 μM) and good repeatability are achieved. The system has potentiality in biochemical research, environmental protection and food industry, owing to its easy operation, rapid response and miniaturization.
