US Patent 7341756 - Metal/bone integration using hydroxyapatite nanoparticles

Medical implants often fail because of failure to integrate artificial components with natural bone. This patent teaches using nanoparticles based on an inorganic mineral found in bone as a fusing agent. Claim 1 reads:

1. A method comprising: chemically charging a surface of a medical or dental implant; and after chemically charging a surface of the implant, forming a layer of crystalline hydroxyapatite nanoparticles on the implant.
