摘要

In this work, pH-sensitive P(CE-MAA-MEG) hydrogel coated with alginate-Ca~(2+)layer was successfully developed, which might be potential application for oral protein/vaccine delivery system. Morphology, swelling behavior, and in vitro release behavior of the alginate/P(CE-MAA-MEG) composite hydrogel were studied in detail. The results confirmed that the alginate/P(CE-MAA-MEG) composite hydrogel showed great pH-sensitivity. The fact that Bovine Serum Albumin (BSA) was released slowly in acidic environment while it was released quickly in neutral medium suggested that the composite hydrogel might be a candidate for protein drugs via oral administration.
