| Popis: | The preparation and properties of mixed Langmuir-Blodgett films of the phospholipid L -α-phosphatidic acid dipalmitoyl and the ionophore valinomycin are described. IR spectroscopy shows clear evidence for the formation of the valinomycin-potassium complex when these layers are immersed in KCl solutions. However, and in contrast to previous studies with fatty acid-valinomycin mixtures, dissociation of the potassium complex is also observed. |
