2H solid-state NMR experiments were performed under magic angle spinning on lipid bilayers orientedinto nanotubes arrays, as a new method to assess the geometrical arrangement of the lipids. Orientationalinformation is obtained from the intensities of the spinning sidebands. The lipid bilayers are formed byfusion of small unilamellar vesicles of DMPC-d54 inside a nanoporous anodic aluminum oxide, either bydirect adsorption on the support or by tethering through a streptavidin/biotin linker. The results supportthat the quality of the lipid bilayers alignment is clearly in favor of the tethering rather than an adsorbedstrategy.
