In suspended membranes formed by spreading artificial bilayer membranes onto microwells fabricated on Si substrates using semiconductor microfabrication techniques, it has been reported that a diffusion barrier exists at the interface between the substrate-supported membrane and the suspended membrane in the case of SiO2/Si substrates. In this presentation, we report on the results of leaflet-specific membrane fluidity measurements using the fluorescence recovery after photobleaching (FRAP) method with asymmetric lipid bilayers, as well as the location of a diffusion barrier.
