Abstract

Self-assembled actin coated membranes showed evidences of buckling instability when a force was applied locally perpendicular to the membrane plane. This instability originated the coupling between out of plane deformations and in-plane strain. Mechanical properties on the microstructures were measured using two beads grabbed with optical tweezers and were bound to a vesicle. A relation between the applied force and the deformation amplitude was obtained by comparing the total energy and the work exerted by the force.
