MICROCAPSULE PREPARATION OF ALGINATE-CHITOSAN ACYL DERIVATIVES, PREPARATION AND APPLICATION THEREOF

摘要

The present invention relates to a product of a microcapsule preparation of alginate-chitosan acyl derivatives, which is produced by mixing microcapsules of alginate-chitosan acyl derivatives with an aqueous solution, wherein a biomicrocapsule structure is divided into two parts, a microcapsule membrane and an inner nucleus; the microcapsule membrane is a polyelectrolyte composite hydrogel membrane formed by chitosan, alginates and chitosan acyl derivatives, and the inner nucleus is an alginate liquid or a hydrogel environment containing cells.
