Biocomposite scaffolds containing chitosan/alginate/nano-silica for bone tissue engineering.

Bone tissue engineering is a promising alternative method for treating bone loss by a combination of biomaterials and cells. In this study, we fabricated biocomposite scaffolds by blending chitosan (CS), alginate (Alg) and nano-silica (nSiO2), followed by freeze drying. The prepared scaffolds (CS/Alg, CS/Alg/nSiO2) were characterized by SEM, FT-IR and XRD analyses.
