| Abstract: | Alginate fiber as a novel drug releasing material was prepared by the treating of sodium alginate with calcium chloride. Bovine serum albumin (BSA), a polypeptide modeling drug, was embedded within fibers. Morphology of the fibers was seen by means of scanning electron microscope (SEM). The swelling property and related mechanism of the fibers were determined, and the loading efficiency and accumulated releasing dynamics of BSA proteins were evaluated. Results showed the concentration of CaCl_2 plays an important role in fiber swelling, mechanic property and protein releasing . |
