Structure of Polyelectrolyte Complexes by the Example of Chitosan Hydrogels with lambda-carrageenan

The views of A.B. Zezin and V.A. Kabanov on the structure of polyelectrolyte complexes of linear polymers are considered and confirmed by studying chitosan hydrogels with lambda-carrageenan formed by regulated gelation. The complexes are visualized by transmission electron microscopy using osmium tetroxide for staining.
