Preparation and Microstructural Study of Gelatin-Chitosan/Carbon Nanotube Composite Scaffolds for Bone Tissue Engineering Applications

The novel chitosan-gelatin scaffolds containing different contents of functionalized multiwall carbon nanotubes, MWCNT, (0-0.01 wt%), were prepared using freeze drying method for bone tissue engineering applications. The prepared composites were characterized by FTIR and FE-SEM. The results showed that the composites with the porosity of 60-95% and pore size of 60-300 μm could be obtained by lyophilization. The porosity of scaffolds was significantly increased with the content of functionalized MWCNT. The findings indicate the potential application of developed novel chitosan-gelatin/MWCNT composite scaffolds in bone tissue engineering
