Abstract
The interaction of iodine with phospholipids has been studied by optical spectroscopic techniques by Bhowmik (1986) and Chatterjee (1988). Iodine’s effect in increasing the electrical conductivity of lipids in solid state films has also been observed (Rosenberg, 1968). The addition of elemental iodine to the solution surrounding black lipid membranes (BLM) results in a large increase in the electrical conductivity of the membranes (Finkelstein, 1968, Liberman, 1968, Jendrasiak, 1969). The iodine induced electrical conduction is believed to occur perpendicular to the phospholipid bilayer for BLM, whereas in the solid state film work reported in this paper, we believe it occurs along the phospholipid head-group layers. Upon iodine adsorption by phospholipid films, optical absorption bands at approximately 294 nm and 365 nm have been observed (Bhowmik et al., 1967).
