| Abstract: | The electrochemical behaviors of Calmodulin(CaM) self-assembled on Au substrate combine with Ca~(2+) under different pH value in the 0.15?mol/L NaCl solution containing 1?mmol/L Fe(CN)_6~(3-/4-) have been investigated and compared with electrochemical impedance spectroscopy techniques systematically.The results demonstrated that the ability of CaM membrane combine with Ca~(2+) in pH=6.5 is stronger than in pH=4.5. |
