Abstract: The issue of the origin of the bending rigidity of a charged membrane formed from amphiphilic molecules is addressed. Electrostatic effects are investigated by direct measurement of the force that is required for deforming a catanionic membrane as function of the ionic strength of the medium by means of an atomic force microscope.
