Abstract: | Progress in the determination of structure and fluctuation spectrum of a floating bilayer system, as well as potential applications for biological studies, is reviewed. The system described here was first introduced by Charitat et al. (Eur Phys J B 8:583–593, 1999) and consists of a planar bilayer floating at 2–3?nm away from an adsorbed one on a solid surface in contact with bulk water. This model has been widely used for surface scattering studies using both neutrons and synchrotron radiation and its use in studies of relevance for physics and biology research areas will be described, together with the progress towards the production of complex biomimetic samples for use with scattering techniques. |
