Synchrotrondiffraction studies on solid-supported membranes in a microfluidicenvironment — •Bert Nickel¹, Christian Reich¹, Marion Hochrein¹, Bärbel Krause² und Joachim Rädler¹ — ¹Ludwig Maximilians Universität, München — ²ESRF, Grenoble

We have developed a microfluidic flow chamber allowing for synchrotron diffraction studies of solid supported membranes at the solid liquid interface using x-ray energies of 20 keV. We demonstrate the potential of the method by comparing three standart preparation methods of lipid bilayers: (a) vesicle fusion, (b) solvent exchange, and (c) spin-coating. A complementary characterization of the solid supported lipid bilayer using fluorescence microscopy is possible.
