Summary This paper concerns the obtention of capsules stabilized by a shell formed by an electrostatic complex which also present an ordered nanostructure. The complex involves chitosan as a semi rigid positively charged polyelectrolyte and sodium dodecyl sulphate (SDS) anionic surfactant. The shell consists of a network in which anionic surfactant micelles crosslink the cationic polymer chains.
