Recycling of Au/ODTMonolayer in the Process of Preparing Au/ODT -PC Bilayer
摘要/Abstract
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
In order to reduce the consumption of gold in the process of fabricating Au supportedoctadecanethiol-phosphatidylcholine( Au/ODT-PC)bilayers, we reuse the Au/ODT monolayers that areobtained by removing PC monolayers from Au/ODT-PC bilayers. The removing procedures are asfollows: Au /ODT-PC bilayers are firstly rinsed with absolute alcohol and then immersed in it for hours.The blocking and structural properties of the recycled Au /ODT monolayers are characterized by cyclicvoltammetry ( CV) and electrochemical impedance spectroscopy ( EIS) . CV and EIS results show that therecycled Au /ODT monolayers have the same CV and EIS behaviors as the newly prepared Au /ODTmonolayers, indicating that the abovementioned method of obtaining recycled Au /ODT monolayers isreliable. However, as the recycling times increase, the blocking property of Au /ODT monolayersbecomes poor. According to CV and EIS results, Au/ODT monolayers can be used three times atmaximun.
