Slip—the relative mobility of the two leaflets in lipid bilayers—represents a generic mechanical-dynamical process. To establish the presence of interleaflet slip in the surface-spreading lipid membranes, the advancing lipid bilayers are exposed to an intense laser spot, which rapidly bleaches the illuminated fluorophores in a radially symmetric shape (see figure).
