Phospholipid monolayers

Interaction of polysilicic acid with monolayers of substances containing quaternary ammonium groups

“…3) results from the depolymerization of polysilicic acid into oligo-and monomer forms [30]. Previous experiments have shown that no interaction occurs with the monomeric form [17,31,32]. In addition, the ortho and disilicic forms have pKa of 9.8 and 10.7, respectively, [24,33,34] so that as time passes and depolymerization proceeds, ionic interaction are reduced due to the diminishing ionization of the silicic acid.…”

Study of the π–A isotherms of miltefosine monolayers spread at the air/water interface

“…On the other hand, although DPPC and DHPC (dipalmityl phosphatidyl choline) have similar p-A isotherms (Fig. 4 D and E), 22 X-ray diffraction studies proved that the inclination of hydrophobic tails is different, i.e. less tilted are molecules which contain an ether bond (DHPC).…”

Action mechanism of water soluble ethanol on phospholipid monolayers using a quartz crystal oscillator

“…However, the molecular areas are ca. 20% larger than those of condensed monolayers, which is 0.42 nm 2 /molecule for DHP and 0.47 nm 2 /molecule for DPPC [47,48]. Therefore, each monolayer in this study is in a 'pre-expanded state' and forms a 'fluid-rich' structure with interfacial structured water.…”
