Abstract
The main objective of the current study is to fabricate a 3D scaffold using alginate hydrogel implemented with carbon nanoparticles (CNPs) as the filler. The SEM imaging revealed that the scaffold possesses a porous internal structure with interconnected pores. The swelling value of the scaffolds (more than 400%) provides a wet niche for bone cell proliferation and migration. The in vitro evaluations showed that the scaffolds were hemocompatible (with hemolysis induction lower than 5%) and cytocompatible (inducing significant proliferative effect (cell viability of 121 ± 4%, p < 0.05) for AlG/CNPs 10%). The in vivo studies showed that the implantation of the fabricated 3D nanocomposite scaffolds induced a bone-forming effect and mediated bone formation into the induced bone defect. In conclusion, these results implied that the fabricated NFC-integrated 3D scaffold exhibited promising characteristics beneficial for bone regeneration and can be applied as the bone tissue engineering scaffold.
