Effects of Calcium and Alginate Concentration on the Calcium-Deficient Hydroxyapatite Hydrogel Bead Formation

Abstract:

Article Preview

The preparation of calcium-deficient hydroxyapatite (CDHAp) beads via immobilization inCa-alginate hydrogel was studied in current research. CDHAp beads of different shapes were preparedby dropwise adding of aqueous CDHAp/Na-alginate suspension to an aqueous and ethanolic Ca(NO3)2solutions. The alginate cross-linking rate was modeled via gelling boundary migration experiment.Prepared beads were washed with deionized water and dried. The beads had lost up to 30% of thediameter comparing to the original after drying.
