Supported bilayers: Combined specular and diffuse X-ray scattering

摘要: A method is proposed for the analysis of specular and off-specular reflectivity from supported lipid bilayers. Both thermal fluctuations “static” roughness induced by substrate are carefully taken into account. Examples bilayers more complex systems comprising a bilayer adsorbed or grafted on another “floating” given. The combined allows precise determination structure floating bilayers, their tension, bending rigidity interaction potentials. We show that this new gives unique opportunity to investigate phenomena like protrusion modes opens way investigation including different kinds lipids, cholesterol peptides.
