| The method might also prove highly valuable for the investigation of surface-active substances other than pulmonary surfactant. |
| Soluble surface-active cationic substances, which have bactericidal effect, remain. |
| It has been shown that such interdigitated lamellar phases are formed with soluble surface-active molecules that interact with the polar headgroups of the lipids. |
| This will then allow observing directly the structure-function relationship of pulmonary surfactant and any other surface-active substance. |
| Such specific interactions may lead to formation of highly surface-active lipid-protein complexes as well as sorting of lipids at the lung air-water interface. |
| An important case of adsorption on liquid surfaces is that of surface-active or surfactant molecules at the water-air or water-oil interface. |
