Probing membranes : Nonspecific interactions between glass beads and supported lipid membranes act as a simple tool to characterize their local structure and mechanical properties. The beads differentiate monolayers (see figure B) from fluid bilayers (A) by inducing a qualitatively different elastic response, characterized by undeformed binding for monolayers and membrane wrapping for bilayers.
