The effect of pH value on the CaM(Calmodulin) self-assembled membrane Au electrode was studied by CV method, where the redox couple of Fe(CN)₆^3-/Fe(CN)₆^4- was employed as a probe. The results indicated the formation of the self-assembled monolayer of CaM that the structure of this membrane is different in various acid/base environment, and the stronger the base, the denser the membrane. The work is meaningful to detect CaM by using electrochemical method.
