In the nervous system, ion channels are essential for all processes. The highly ordered porous anodic aluminum oxide (AAO) was modified at the interface between two immiscible electrolyte solutions (ITIES) to recover the process of ion transfer through the ion channels. The study on dynamic process of ion transfer through the ion channels obtained for DK+0 is 1.40 脳 10鈭? cm2 s鈭? and DNa+0 is 2.74 脳 10鈭? cm2s鈭?. The result offers tremendous advantages for linear relationship between the half-wave potential and concentration of K+ and Na+. In addition, it will be helpful to understand both the mechanism about the dynamics and thermodynamics processes of ion transfer through the ion channels and the role about ionic concentration in nerve conduction.
