Kinetics of the formation of a phospholipid multilayer on a silica sol surface

Аннотация

The ordering of a multilayer consisting of DSPC bilayers on a silica sol substrate is studied within the modelindependent approach to the reconstruction of profiles of the electron density from X-ray reflectometry data. It is found that the electroporation of bilayers in the field of anion silica nanoparticles significantly accelerates the process of their saturation with Na⁺ and H₂O, which explains both a relatively small time of formation of the structure of the multilayer of 1–7×10⁵ s and ~13% excess of the electron density in it.
