MWCNTs and SWCNTs based Nanocomposites for Cartilage and Bone Tissue Regeneration

Zhang L.G., Holmes B., The George Washington University, US

Cartilage and bone defects, which are caused by a variety of reasons such as traumatic injuries, osteoarthritis, osteoporosis or bone cancers, represent common and severe clinical problems. Developments in nanotechnology and tissue engineering have provided [...]

Nano-hydroxyapatite and/or nano-silk fibroin as bone graft materials

SG Kim, Gangneung-Wonju National University, KR

Electrospunned silk fibroin has been considered as scaffold for tissue engineering. Particularly, it has been used for bone regeneration with nano-hydroxyapatite (nHA). Though some papers showed successful results of bone regeneration in nHA and electrospunned [...]

Evolutionary selection of bone mineral hydroxyapatite binding peptide using landscape phage library

Modali S., Abbineni G., Jayanna P., Petrenko V., Mao C., University of Oklahoma, US

Hydroxyapatite [(Ca5(PO4)3OH)2] is a biomineral which is associated with bone proteins to form mineralized extracellular matrix in a mature bone. Using two landscape phage libraries, in which random octa-peptides and nona-peptides are displayed on all [...]

Osteogenic induction on single-walled carbon nanotube scaffolds

Zanello L.P., Sharma P., Corzano R., Hauschka P., University of California Riverside, US

Production of bone materials is the result of secretory activities by osteoblasts, the bone-forming cells. In the fractured and wounded bone, successful repair and/or regeneration depends on the capacity of osteoblast precursors to proliferate and [...]

Enzymatically Degradable Hydrogel Nanocomposite for Bone Regeneration

Jabbari E., He X., Sarvestani A.S., University of South Carolina, US

One approach to bone replacement involves the use of in-situ crosslinkable scaffolds for cell transplantation to promote tissue growth, nutrient diffusion, matrix production, and vascularization. Bone matrix is a composite material consisting of aqueous and [...]
