The lack of deformation combined with the fact that we can readily describe the scattering curves by adjusting the SLD contrast such that the internal and external salt concentrations are equal, when the vesicles have been incubated with AMPs, demonstrates transport of salt. This is expected as the permeabilization of lipid membranes has previously been demonstrated for both indolicidin and LL-37 using assays with large fluorophores. However, in the present case we directly and simultaneously probe the permeability of monoatomic ions in addition to the overall vesicles and membrane structures. These results demonstrate that peptides can effectively facilitate ion transport, even when only inserting into the outer leaflet and causing minimal structural changes to the membrane. This is particularly noteworthy for indolicidin given its short and unstructured nature. Moreover, these results are in excellent agreement with the previous studies which demonstrated that these peptide, at these PL ratios, have almost no effect on the membrane structure . They also show that, even in the absence of structural effects and pores, AMPs can permeabilize the membrane, as was hypothesized in the aforementioned studies.
