PREPARATION AND CHARACTERIZATION OF POROUS HYDROXYAPATITE AND ALGINATE COMPOSITE SCAFFOLDS FOR BONE TISSUE ENGINEERING

Objective: To prepare and characterize composite scaffolds of a hydroxyapatite (HA) and an alginate having high viscosity.Materials and Methods: HA powder was synthesized using wet chemical precipitation, the alginate powder was extracted from the Sargassum duplicatum seaweed, and the HA/alginate composite scaffolds were prepared by freeze-drying. X-ray diffraction and Fourier transform infrared techniques were utilized to characterize the HA...
