A supported lipid bilayer membrane (s-BLMs) formed on a freshly cleaved metallic surface by the Tien method was applied for the design of an electrochemical sensor for detection of neutral odorant molecules. The lipid bilayer was modified by saturation with fullerene C(60), which possesses electron mediator properties and facilitates a redox reaction occurring at the border of the lipid membrane and metal surface. I(2)/I(-) and ferrocenyl trimethyl bromide were used as electroactive marker ions. The smell compounds adsorb on the surface of the lipid layer and change its structure. As a consequence the ratio of marker ion penetration to the lipid membrane is altered. The magnitude of these changes depends on the amount and chemical structure of adsorbed molecules. The research presented was carried out by cyclic voltammetry. The magnitude of the electrochemical signal generated by smell compounds was correlated with other parameters describing their molecular properties such as: octanol/water partition coefficients and dipole moments.
