X-ray measurements of bovine red blood cells in continuous flow — •Jan-Philipp Burchert1, Gerrit Brehm1, Rita Graceffa1, Manfred Burghammer2, and Sarah Köster11Institut für Röntgenphysik, Georg-August-Universität Göttingen, Germany — 2European Synchrotron Radiation Facility, Grenoble, France

Due to their high penetration depth and resolution, X-rays are ideally suited to study structures and structural changes within biological samples. For this reason, X-ray-based techniques have been used by various authors to investigate adhesive cells on solid supports. However, these techniques cannot conveniently study suspended cells in flow. We developed an X-ray compatible microfluidic device that serves as a sample delivery system and measurement environment. In our experiments, this device is applied to measure fixed bovine red blood cells by small-angle X-ray scattering (SAXS). We find a good agreement between in-flow and static SAXS data. Thus, we demonstrate that suspended cells can be measured with SAXS in continuous flow.
