The deposition and characterization of phosphatidic acid Langmuir-Blodgett films

The deposition of Langmuir-Blodgett films of the calcium salt of the phospholipid 1,2-dipalmitoyl- sn-glycero-3-phosphatidic acid is described. The layers have been investigated using the techniques of IR spectroscopy and ellipsometry. These methods reveal reproducible film deposition, up to 80 mono...

Description
Summary:The deposition of Langmuir-Blodgett films of the calcium salt of the phospholipid 1,2-dipalmitoyl- sn-glycero-3-phosphatidic acid is described. The layers have been investigated using the techniques of IR spectroscopy and ellipsometry. These methods reveal reproducible film deposition, up to 80 monolayers, with an average thickness per layer of 2.7 nm. The use of the multilayer structure as a host for molecules of the ionophore valinomycin is also briefly discussed.
