| Abstract: | Electrochemical impedance spectroscopy of self-assembling cyclic peptide membrane bonded Ca~(2 )in the solution of [Fe(CN)_6]~(3-/4-)at different times were determined.The results indicated that the relation of resistance of membrane and the time of immersing in CaCl_2 solution manifested deferent rule with the content of CaCl_2 solution.According to experimental results,the manner of CPCBC molecule bonded to Ca~(2 ) was supposed. |
