ALGINATE-e-POLYLYSINE MICROCAPSULE, ITS PREPARATION METHOD AND APPLICATION

摘要

An alginate-e-polylysine microcapsule for embedding bioactive substances and its preparation method are disclosed. The microcapsule is a sphere with particle size of 100-1000 µm, which comprises microcapsule film and inner core. The microcapsule film is a polyelectrolyte complex hydrogel film obtained by reacting alginate withe-polylysine via static complexation. The inner core is a fluid- or hydrogel-environment comprising bioactive substances. The microcapsule is used as the carrier for cell transplantation, cell culture or embedding bioactive substances such as protein, polypeptide, enzyme or nucleic acid.
