HYDRATION OF DPPC MONOLAYERS AT THE AIR/WATER INTERFACE AND ITS MODULATION BY THE NONIONIC SURFACTANT C(12)E(4) - A NEUTRON REFLECTION STUDY

Abstract:

The hydration of a phospholipid monolayer of dipalmitoylphosphocholine (DPPC) at the air/water interface is studied for different lateral pressures which correspond the the fluidlike I and LE phases and to the solidlike S phase using the neutron reflection technique. This method enables for the first time a precise determination of the number (nw′) of water molecules per DPPC headgroup as a function of monolayer phase state. Furthermore, the effect of the presence of the nonionic surfactant p...
