Outline of Final Research Achievements

We developed the formation technique for “Bioimplants”, integrating medical experiences into engineering techniques. It is important to produce the hydrophilic surface in order to adsorb the several kinds of protein on the metallic, ceramics, and polymer implants. In this research, we found hydro-techniques for the super-hydrophilicity of these implants and for keeping the super-hydrophilicity. Several kinds of protein were adsorbed on the super-hydrophilic implants surfaces (bioimplant). Important proteins were found for the improvement of the osteoconductivity by the implantation of the protein-adsorbed samples in rats’ tibia.
