Funded Activity Summary

Surface engineering of biomaterials for optimal bone bonding characteristics. The ideal bone-implant material is hydroxyapatite. Chemically similar to bone mineral, hydroxyapatite is capable of inducing bone ongrowth. An ideal surface coating for metal hip implants, plasma spraying has been the preferred commercial hydroxyapatite coating technique. Until recently, it was always presumed that the bioactivity of hydroxyapatite resulted from its surface chemistry. However, a recent study has shown that the bioactivity of HAp coatings strongly correlates with surface roughness on the scale of bone cells. This project will explore cell-attachment behaviour for hydroxyapatite coatings prepared by plasma spraying compared with engineered surface morphology/chemistry by microlithography and vapour coating.
