7_08/2006Cover Picture: Glass Bead Probes of Local Structural and Mechanical Properties of Fluid, Supported Membranes (ChemPhysChem 8/2006)

The cover picture shows a spatial pattern of morphology-dependent elastic response of supported membranes to gravitationally settled microscopic glass beads. Beads differentiate lipid monolayers (red regions) from fluid bilayers (yellow regions) by inducing a qualitatively different elastic response, characterized by nondeformed binding for lipid monolayers (uncoated beads) and a wetting or membrane wrapping for bilayers (membrane wrap enveloping the beads). These results presented by Parikh et al. on page 1678 indicate the importance of interleaflet coupling and bilayer fluidity in determining elastic response of supported membranes. They also suggest a new, simple technique to probe mechanical properties of substrate-supported fluid membranes. The art work was designed by James Evans.
