TCNQ修饰的金/18硫醇-卵磷脂双层膜在Fe(CN)_6^(3-/4-)溶液中的单向导电性

One Direction Conductivity of TCNQ Modified Au/Thiol Lipid Bilayer in Fe(CN) 3 /4 6 Solution

固体支撑的双层类脂膜不仅是研究和模拟发生在生物膜上各种过程的重要模型，而且也成为研制生物分子电子器件的重要工具．在固体支撑的双层类脂膜中，金／硫醇－类脂双层膜以其缺陷少、稳定性高等特性而倍受关注［１］．本文报道了修饰７，７，８，８－四氰基奎诺二甲烷（...

The Au supported octadecanethiol phosphatidylcholine bilayers embedded with TCNQ(7,7,8,8 tetracyanoquinodimethane)were investigated using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS).EIS indicates that the Faraday resistance of the unmodified bilayers is 5 times greater than that of TCNQ modified bilayers in Fe(CN) 3 /4 6 solution.CV shows that the modified bilayers exhibit an increase in conductance in one direction.
