Chitosan/hydroxyapatite-based composites
In the past 20 years, there has been a growing trend towards the development and use of biomaterials for the repairing and restoration of damaged bone tissue. The calcium phosphate bioceramics have attracted great attention in the field of orthopaedics because of its similarity to the mineral component of bone tissue. They have been used as granules for example in non-load bearing small implant...
متن کاملReduced graphene oxide-coated hydroxyapatite composites stimulate spontaneous osteogenic differentiation of human mesenchymal stem cells.
Human mesenchymal stem cells (hMSCs) have great potential as cell sources for bone tissue engineering and regeneration, but the control and induction of their specific differentiation into bone cells remain challenging. Graphene-based nanomaterials are considered attractive candidates for biomedical applications such as scaffolds in tissue engineering, substrates for SC differentiation and comp...
متن کاملCollagen-hydroxyapatite composites for hard tissue repair.
Bone is the most implanted tissue after blood. The major solid components of human bone are collagen (a natural polymer, also found in skin and tendons) and a substituted hydroxyapatite (a natural ceramic, also found in teeth). Although these two components when used separately provide a relatively successful mean of augmenting bone growth, the composite of the two natural materials exceeds thi...
متن کاملSurface modifications of glass-reinforced hydroxyapatite composites.
Surface modifications of glass-reinforced hydroxyapatite composites immersed in a simulated physiological solution were studied using X-ray photoelectron spectroscopy, scanning electron microscopy and energy dispersive X-ray spectroscopy. In the first stages of the apatite formation process, calcium and silicon ions were leached out from the surface of the composites. After 12 days of immersion...
متن کاملComposites Hydroxyapatite with Addition of Zirconium Phase
Osteoporosis is a disease in which the density and quality of bone are reduced, leading to weakness of the skeleton and increased risk of fracture. Osteoporosis literally means "porous bone". When a bone has become osteoporotic or osteopenic (low bone mass), the risk of a fracture increases. The forearm, spine and hip are the most common fracture sites, accounting for more than 80 percent of al...
