Highly osteogenic and mechanically strong nanofibrous scaffolds based on functionalized multi-walled carbon nanotubes-reinforced electrospun keratin/poly(ε-caprolactone)

Here, we fabricated the electrospun scaffolds (so called PCL/Kr and PCL/Kr/CNT) based on poly(ε-caprolactone) (PCL), keratin (Kr), and carboxylated multiwalled carbon nanotubes (CNTs-COOH). Our goal was to evaluate the effect of CNTs-COOH on the osteogenic differentiation and mechanical and physicochemical properties of the scaffolds. We found that the addition of CNTs-COOH to the PCL/Kr scaffold reduced the average fiber diameter from 123 to 55...
