Porous nanocomposite scaffolds were fabricated by freeze casting method with composition of constant chitosan concentration (3 wt.%) blended with different percentages of (10, 20 and 50 wt.%) bioactive glass nanoparticles (BGNPs) which were synthesized by sol-gel method. Transmission Electron Microscopy (TEM) images proved that the size of synthesized BGNPs with formula of 64Si02.28Ca0.8P205 was lower...
Collagen-apatite (Col-Ap) scaffolds have been widely employed for bone tissue engineering. In the current study, we fabricated Col-Ap hydrogels with a biomimetic structure and freeze-dried Col-Ap hydrogels with a hierarchical lamellar structure. Col-Ap hydrogel was prepared using a biomimetic approach combining self-assembling of collagen molecules with simultaneous mineralization in a modified simulated...
