Electric polarization and size of lipid nanotubes—an electric light scattering study

Self-assembled lipid nanotubes (LNTs) could mimic the lipid bilayer of biological membranes and are widely used as substrates for proteins in the biotechnology. Since the protein-LNT binding depends strongly on the physicochemical properties of the LNT, we studied one of the important properties of the “naked” (not associated with protein) LNT—their electrical polarizability. The experiments were performed on galactosyl ceramide nanotubes...
