| Outline of Final Research Achievements |
We have succeeded in preparing for the chitin nanofibers from crab shell. The chitin nanofiber has 10 nm in diameter, efficient mechanical properties, and variety of biological properties. In this study, a calcium phosphate/chitin nanofiber composite material was prepared for bone tissue engineering. Chitin nanofiber offered a useful template with which to form calcium phosphate crys-tal as with the biomineralization of crab shell in nature. Calcium phosphate improved the mechanical properties of the hydrogel. This unique inorganic/organic nanocomposite modeled on nature is expected to expand the application of chitin nanofibers in medical and dental fields by utiliz-ing their morphological, mechanical, and biological properties.
