Abstract:

The electrochemical behavior of self-assembled n-dodecanethiol monolayer and n-dodecanethiol/phosphatidylcholine hybrid bilayer modified HMDE in different concentration of Fe(CN)63-/4- solutions has been studied by using cyclic voltammetry and electrochemical impedance spectroscopy measurements. The equivalent circuit of different system have been put forward. We also calculate the normal electron tunneling rate constant k0 and the apparent thickness d of the membrane.

Key words: Hanging mercury drop electrode(HMDE), Self-assembled monolayer, Self-assembled bilayer
