ELECTRON MICROSCOPY AND DIFFRACTION STUDY OF PHOSPHOLIPID MONOLAYERS TRANSFERRED FROM WATER TO SOLID SUBSTRATES.

The nature of the condensed states of phospholipid monolayers is studied by transmission electron microscopy. The layers were transferred from air/water interface to carbon films, to crystalline layers of graphite oxide and to Formvar foils covered with SiO//2. Platinum shadowing at 15 degree angle of incidence layer thickness could be determined to an accuracy of about 10% allowing to distinguish between monolayers and multilayers unambiguously.
