医用セラミックスに関する基礎研究とバイオインスパイアード材料開発への展開

Abstract

Certain types of ceramics have property that shows direct bonding to living bone tissue in vivo, and are referred to as bioactive materials. As a bioactive material, Bioglass® was discovered and developed in early 1970’s, inorganic glasses and materials based on them have been studied for bone substitutes for tissue repairing. In addition, elucidation of the mechanism by which they express their high biological affinity has been studied. The author has been interested in elucidating the mechanisms by which inorganic glasses show high biological affinity to bond to living bone, and has carried out fundamental research, as well as developing novel biomaterials based on the materials chemistry of glasses and ceramics. The science and technology of the bioactive glasses have made a significant contribution to the field of medicine. Whilst, 2022 has been designated as the International Year of Glass by the United Nations General Assembly, and events commemorating the science, technology and art associated with glass are being held around the world. As part of these events, a special feature on glass science and bioinspired materials was also held at the 2022 Spring Meeting of the Japan Society of Powder and Powder Metallurgy. Against this background, this paper describes the review of the author’s achievement awards, with a particular focus on glass and biomaterials, and the development of novel materials using bioinspired methods.
