Open publisher page 4 citations

Abstract

The chitosan sodium alginate microcapsules for injectable usage were prepared by emulsification method. The diameter of microcapsules is less than 200 micron and posses a relative narrow and normal gauss distribution. The loading efficiency of Bovine Serum Album(BSA) in microcapsules is more than 50%. By the coating with chitosan on the surface of sodium alginate microcapsules, the BSA release from microcapsules is extended from several hours to more than half a month.
