High resolution structure analysis of model membrane systems by x-ray reflectivity is typically performed using stabilizing solid supports, which have shown to strongly interact with the membranes and can severly affect the membranes functionality. To circumvent these restrictions free-standing lipid model membranes, also called Black Lipid Membranes (BLMs), have been used in this work towards a novel type of structural assay based on x-ray phase contrast imaging. Bulged lipid bilayers fully immersed in buffer solution have been visualized by a transmitted plane or spherical x-ray wave front in the Fresnel regime after free space propagation. The development of the experimental system and the image analysis enables a quantitative investigation of the membranes structural properties in a localized membrane patch. In future this technique can be used to study the structure of membranes and more generally ultrathin films in functional and physiological environments and under out-of-equilibrium conditions. dc.format.extent 1-140 dc.language.iso eng dc.publisher Universitätsverlag Göttingen dc.identifier.bibliographicCitation Göttingen series in x-ray physics; 1 dc.rights openAccess dc.rights.uri http://creativecommons.org/licenses/by-nd/2.0/de/ dc.subject.ddc 530 dc.title Black lipid membranes studied by x-ray phase contrast imaging dc.type monograph dc.subject.gok WCC 000 dc.subject.gok RQE 900 dc.subject.bk 42.12 dc.subject.bk 33.05 dc.publisher.place Göttingen dc.type.version publishedVersion dc.type.subtype monograph dc.description.status peerReviewed
