X-Ray Scattering of Lipid Membranes
X-ray scattering probes positional correlations on molecular to supramolecular length scales. Here, we focus on its application to lipid membranes.
Understanding the function of biological membranes is intimately coupled to determining their structure and their related dynamics. Lipid membranes, that is, biological membranes devoid of protein and carbohydrate networks, are highly useful models in understanding certain aspects of biological membranes. Dispersed in an aqueous solution, membrane lipids form an array of structures, which are highly dependent on their molecular chemistry (shape), as well as on the properties of their surrounding solution (e.g., pH, ionic strength, hydration, temperature, and pressure). X-ray techniques offer a probe-free and noninvasive toolset to study positional correlations of lipid aggregates on various length scales. These positional correlations may either originate...
