Paper Abstract

Polarized FTIR-ATR spectroscopic studies of Langmuir-Blodgett (LB) multilayers of dipalmitoylphosphatidic acid (DPPA) show a high degree of order in multilayer films, with the alkyl chains approximately parallel to the substrate normal. FTIR-ATR spectroscopy has also shown that biological bilayers of DPPA, made by LB deposition, have trapped water which diffuses slowly through the bilayer, on a time sale of 2 - 3 hours.
