Abstract: Neutron spin echo spectroscopy has been used under grazing incidence conditions to study the dynamics of SoyPC phospholipid membranes at the solid-liquid interface. The use of advanced neutron optical components such as a neutron prism and a resonator structure at the interface for an increase in intensity near the interface helped to study partially elastic waves in the phospholipid membrane as well as the influence of Ibuprofen on the membrane elasticity. Previously observed phase transitions of the surface layers of SoyPC from a lamellar structure to surface crystalline phases also showed their imprint in a suppresion of the phospholipid membrane dynamics.
