Evaluation of Cationic Biopolymers for the Design of Silica-coated Alginate Capsules

Lysozyme and chitosan were evaluated as cationic polymers for the design of silica-coated alginate capsules. No direct relationship was found between the strength of the bio-organic poly-electrolyte membrane and the stability of capsules after the silica coating, which depends mainly on the nature of poly-cation/silicate interactions.
