Evaluation of the effects of keratin on physical, mechanical and biological properties of poly (3-hydroxybutyrate) electrospun scaffold: Potential application in bone tissue engineering

Proper selection of materials and methods of construction are important factors in scaffolding in tissue engineering. In this research, a novel biomimetic scaffold containing poly (3-hydroxybutyrate) (PHB) and keratin (5–15 wt. %) was prepared by the electrospinning method. The results showed that all electrospun scaffolds have 3D structures with high interconnected porosity and hydrophilicity. FTIR, Raman and 1H-NMR indicated the presence of...
