A Lipid Photoswitch Controls Fluidity in Supported Bilayer Membranes.

Supported lipid bilayer (SLB) membranes are key elements to mimic membrane interfaces on a planar surface. Here, we demonstrate that azobenzene photolipids (-) form fluid, homogeneous SLBs. Diffusion properties of - within SLBs were probed by fluorescence microscopy and fluorescence recovery after photobleaching.
