摘要
BLM(双层类脂膜)的金属支撑构成了一种电化学传感器。这种传感器的化学反应和电现象之间的转化,是通过金属对BLM的支撑来实现的,不同于经典的电化学换能器。用缬氨霉素修饰的BLM作为敏感膜,制成金属-BLM和经典电化学K+离子电极。通过两种电极对K+离子检测的对比实验,以及不同直径和新鲜面不同给出方法的金属-BLM电极的对比实验,探讨了BLM的金属支撑对BLM的K+离子敏感特性的影响。从实验数据看,BLM的金属支撑在性能上优于经典电化学传感器,但支撑介质的新鲜面对BLM的K+离子敏感特性有影响。
The metal support of bilayer lipid membrane（BLM） is used as an electrochemical sensor. The conversion between chemical reaction and electric phenomenon of the sensor is finished by the metal support for BLM,which is different from classical electrochemical transducer. MetalBLM potassium ion electrodes and classical electrochemical ones were prepared using BLM modified by valinomycin as their sensing membranes. Through the contrastive experiments to measuring potassium ions with that two prepared electrodes and the contrastive experiments to measuring potassium ions using electrodes with diverse diameter and different fresh surface. The effect of the sensitive properties of metal support of BLM to potassium ions was studied. By analyzing the experimental data, it was found that metal support of BLM was superior to classical electrochemi- cal sensor on properties and the different fresh surface of supporting medium affected the sensitive properties of potassium ions of BLM.
