Abstract

Abstract : On page 6338, N.‐J. Cho and co‐workers use particle tracking to measure the diffusional motion of nanosized lipid vesicles that are electrostatically adsorbed onto a solid supported lipid bilayer (SLB). The vesicle motion is coupled to that of a nanoscopic lipid cluster in the upper leaflet and induces slippage between the upper and the lower leaflets of the SLB. This approach provides an alternative to existing methods for measuring the interleaflet friction coefficient and membrane viscosity.
