| Research Abstract |
There is a rapidly increasing number of patients with diseases of their hard-tissue and, given current demographic trends in today's society with a large number of elderly people ; this is an important global problem with severe financial implications.
In general, hydroxyaptite (HAp) ceramcis, which bonds directly with host bone, is one of a new generation of excellent bioactive materials ; however, HAp has some problems, such as lack of osteoinductivity and relatively inferior mechanical properties as compared with natural bone. In order to overcome the above problems and to provide a high quality of life (QOL) for the aged, we plan to develop novel, high performance biomaterials though control of nano-interface.
Firstly, we performed the examination study on the development and evaluation of ceramics in medicine through control of nano-interface at 2005 including a bibliography. Thus, we have arrived at a concept of "apatite genomics" which the apatite ceramics give an affect to gene expression of cells, such as osteoblast and osteoclasts, based on control of nano-interface between HAp ceramics and cells. We believe that this concept create novel biomaterials with high-performance properties.
In addition, we have organized a session "the development and evaluation of ceramics in medicine through control of nano-interface" of 18^<th> Fall Meeting of The Ceramic Society of Japan at the 28^<th>-29^<th> September 2005 in Osaka, and then our reviews have been published to Journal of Japanese Society for Biomaterials.
