“Self-assembly of mixed charge amphiphilic systems and X-ray investigation of their elastic properties”

Electrostatics drives highly disordered systems towards highly ordered self-assembled structures. Many charged molecules of opposite charges form ordered ionic assemblies. Examples of biological ionic structures include viruses. These systems are simple enough to be described by physical and mathematical laws, and also complex enough to have important activity. A system of amphiphilic molecules self-assemble in water into various domains like vesicles, micelles and membrane layers. Despite the large morphological complexity of biological membranes, surprising amount of insight about their shape can be deducted from simple elastic models with only a handful of parameters. The shapes that amphiphilic molecules form are determined mainly by the aggregate's elastic properties, including bending rigidities, spontaneous curvature and surface tension. I will discuss the theoretical and experimental aspects in search for the elastic properties of amphiphilic membranes
