| Abstract: | Abstract— Ultraviolet light flashes induced voltage transients across bilayer lipid membranes when aromatic amino acids were adsorbed to one side of the membrane. These photo-effects varied with the chromophore structure, the aqueous solution salt concentration, pH and oxygen partial pressure. These photo-effects are attributed to the migration of electrically charged photochemical intermediates in the membrane, and provide a new method for studying the effects of UV light on membranes. |
