Formation of multilamellar vesicles ('onions') in peptide based surfactant.
Concentration dependent morphological characteristics of a novel dipeptide derivative Lys-Asp-Lauryl.HBr (1) has been presented. Evidence for "onion" like vesicle formation at higher concentration (>8.2 x 10(-3) M) of peptide (1) in aqueous medium was obtained from conductance and 90 degrees light scattering measurements, and cryo-transmission electron microscopic studies.
