Nanocomposites for artificial bone (July 2007) - News - nanotechweb.org
Human bone is mainly composed of 65% hydroxyapatite nanocrystals and 25% collagen fibres. In dentine, which is found in teeth, this changes to about 70% hydroxyapatite and 20% collagen.
Scientists have tried to make nanosized artificial bone materials using various methods before now and have recently turned their attention to mineralised collagen, a nanoapatite/collagen composite. This material is highly biocompatible and has the nanostructure of artificial bone. It could be used in bone grafts and bone-tissue engineering, among other applications.
