                      hemolytic saponin, digitonin, on model lipids cholesterol
                      and dipalmitoylphosphatidylcholine (DPPC) using a
                      combination of tensiometric (surface pressure and
                      dilatational surface elasticity), spectroscopic (infrared
                      reflection absorption spectroscopy, IRRAS), microscopic
                      (fluorescence microscopy), and scattering techniques
                      (neutron reflectivity, NR, and grazing incidence X-ray
                      diffraction, GIXD). The monolayers of individual lipids and
                      their 10:9 (mol/mol) mixture were exposed to an aqueous
                      solution of digitonin (10–4 M) by subphase exchange using
                      a setup developed recently in our laboratory. The results
                      confirm that digitonin can adsorb onto both bare and
                      lipid-covered water–air interfaces. In the case of DPPC, a
                      relatively weak interaction can be observed, but the
                      presence of cholesterol drastically enhances the effect of
                      digitonin. The latter is shown to dissociate the weak
                      cholesterol–DPPC complexes and to bind cholesterol in an
                      additional layer attached to the original lipid monolayer.},
