Nano-hydroxyapatite composite biomaterials for bone tissue engineering--a review

J Biomed Nanotechnol. 2014 Oct;10(10):3124-40. doi: 10.1166/jbn.2014.1893.

Abstract

In recent years, significant development has been achieved in the construction of artificial bone with ceramics, polymers and metals. Nano-hydroxyapatite (nHA) is widely used bioceramic material for bone graft substitute owing to its biocompatibility and osteoconductive properties. nHA with chitin, chitosan, collagen, gelatin, fibrin, polylactic acid, polycaprolactone, poly(lactic-co-glycolic) acid, polyamide, polyvinyl alcohol, polyurethane and polyhydroxybutyrate based composite scaffolds have been explored in the present review for bone graft substitute. This article further reviews the preparative methods, chemical interaction, biocompatibiity, biodegradation, alkaline phosphatase activity, mineralization effect, mechanical properties and delivery of nHA-based nanocomposites for bone tissue regeneration. The nHA based composite biomaterials proved to be promising biomaterials for bone tissue engineering.
