A challenging task remains the study of cells by x rays in their natural, aqueous environment. Here, we overcome this limitation by presenting scanning x-ray diffraction measurements with beam sizes in the range of a few hundred nm on living and fixed-hydrated eukaryotic cells in microfluidic devices which mimic a native environment. The direct comparison between fixed-hydrated and living cells shows distinct differences in the scattering signal, pointing to structural changes on the order of 30 to 50 nm."],["dc.identifier.doi","10.1103/PhysRevLett.112.088102"],["dc.identifier.gro","3142182"],["dc.identifier.isi","000331957600012"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/5443"],["dc.language.iso","en"],["dc.notes.intern","WoS Import 2017-03-10"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.eissn","1079-7114"],["dc.relation.issn","0031-9007"],["dc.relation.orgunit","Institut für Röntgenphysik"],["dc.relation.workinggroup","RG Köster (Cellular Biophysics)"],["dc.subject.gro","x-ray imaging"],["dc.subject.gro","x-ray scattering"],["dc.subject.gro","cellular biophysics"],["dc.subject.gro","microfluidics"],["dc.title","Scanning X-Ray Nanodiffraction on Living Eukaryotic Cells in Microfluidic Environments"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]
