| Outline of Final Research Achievements |
In order to develop excellent biomaterials used in the water-containing state in human body, new NMR methods i.e., 13C solid state NMR, 1H solid state NMR and 2H solution relaxation NMR methods for analysis of hydrated materials were developed. These were applied to obtain the detailed information on the structure and dynamics of hydrated silk, and dynamics of water molecules interacted with silk, which was used to optimize the coating of silk on the silk bases. The artificial silk grafts were prepared and implanted in mouse, rat and dog to evaluate the ability of the graft. By repeating NMR analysis, preparation of the graft and animal implantation, the artificial silk graft with small diameter was developed.
