Abstract
The redox reactions for a solid supported BLM electrode containing vinyl-ferrocene as an electron mediator in glyceryldioleate dissolved in squalene with a Teflon coated wire (Pt or SS) as a solid support have been investigated using cyclic voltammetry. The results have shown that (i) ferrocene can be very easily immobilized on the surface of a metallic electrode by the new supported BLM (s-BLM) system. This demonstrates that the s-BLM system offers a novel approach to the electrode modification by simple way of immobilization of compounds within BLM, and (ii) ferrocene in a bilayer lipid membrane increases about two orders of magnitude a potassium cyanide ion sensitivity of the platinum electrode.Keywords
