ABSTRACT:
Hydroxyapatite is treated by a combination of nitridation and the application of bone morphogenetic protein or DNA encoding such a protein to improve the tissue compatibility and affinity of the hydroxyapatite, rendering the hydroxyapatite more useful as a material for biomedical implants.
