将实验后的金 /正 1 8硫醇 -卵磷脂 ( Au supported octadecanethiol-phosphatidylcholine,Au/ODT-PC)双层膜用无水乙醇冲洗并浸泡数小时后以除去卵磷脂 ( phosphatidylcholine,PC)层 .电化学研究表明 ,这样重新得到的金 /硫醇 ( Au supported octadecanethiol,Au/ODT)单层膜与用自组装法新制备的 Au/ODT单层膜具有相同的循环伏安和交流阻抗性质 ,而且仍保持着其原来的完整性 ,在制备双层膜的过程中可以有限次地重复使用 After the experiment, the Au / octyldecanethiol-phosphatidylcholine (Au / ODT-PC) bilayer membrane was rinsed with anhydrous ethanol and soaked for several hours to remove the phosphatidylcholine (PC) layer Electrochemical studies show that the gold / thiol (Au / octanodeoxythiol, Au / ODT) monolayer thus obtained has the same cyclic voltammetry and AC impedance properties as the Au / ODT monolayers newly prepared by the self-assembly method , And still maintain its original integrity, can be used repeatedly for a limited time in the preparation of bilayer films
