Abstract

The influence of K₇Fe³⁺P₂W ₁₇O₆₂H₂ on l-α -phosphatidylcholine/cholesterol bilayer lipid membrane on Pt electrode was studied by voltammetry and AC impedance spectroscopy. The interaction of the polyoxometalates with the BLM can promote the access of Ru(NH₃) ₆³⁺ and [Fe(CN)₆]^3-/4- to the electrode surface. It was found that some kind of pores had been formed on the BLM by AFM. The phenomenon is attributed to the interaction of K ₇Fe³⁺P₂W₁₇O₆₂H ₂ with phosphatidylcholine phosphate groups located in its outer leaflet. Experimental results are helpful to understand the biological activity of the polyoxometalates in vivo.
