Abstract
This paper reports a novel biomimetic technique for obtaining chitosan–calcium phosphate composite scaffolds (Cs–CP) by calcium phosphate precipitation from its precursors,CaCl 2 and NaH 2PO 4 in the presence of ammonia and Cs, followed by product freeze-drying. The structural and morphological analysis showed the arrangement of CP onto Cs fibers, while Cs acting as glue to bind together the CP crystals. The presence of different forms of CP was evidenced, including hydroxyapatite, which is known to be involved in the formation of the new bone tissue in living organisms. Great mechanical properties of the scaffolds indicate their potential use in bone tissue engineering.
