Abstract
The effect of Ca2+ on the electron transfer of Fe(CN)(6)(3-/4-) couple at Pt supported lecithin (PC)/cholesterol (CH) bilayer lipid membrane (BLM) electrode has been studied by voltammetry and ac impedance spec troscopy. Experimental results suggest that the interaction of Ca2+ wi th the BLM can open some kind of channel for Fe(CN)(6)(3-/4-) ions, al lowing increased access of the redox couple to the electrode surface. This phenomenon may be related to the Ca2+ regulation or activation ef fect of ion channel in some biomembranes. (C) 1998 Elsevier Science S. A.
