The Laboratory of Biomaterials (Professor AIZAWA Mamoru) focuses on hydroxyapatite, which is the inorganic main component of biological bone and teeth, and is promoting basic and applied research on biomaterials that can be applied to artificial bones. This paper verified the usefulness of Hard X-ray Photoelectron Spectroscopy (HAXPES) as a new analytical method to study proteins adsorbed on material surfaces using hydroxyapatite ceramics as a model. HAXPES is a method for evaluating semiconductors in which Professor OGURA Atsushi of the Department of Electronics and Bioinformatics specializes, and this research is the result of our collaboration in different fields.

The Ceramic Society of Japan was established in 1891 for the purpose of developing the industry, science and technology of ceramics, and is Japan's only comprehensive, collaborative academic and industrial organization for ceramics. J. Ceram. Soc. Jpn. is the academic journal of the organization. The 2024 JCS-JAPAN Best Student Paper Award is awarded to the paper whose first author is a student member at the time of submission and is a member at the time of selection, among all papers published in the January to December 2024 issues, by the committee chair after being selected by the selection committee from among the submitted papers and approved by the editorial committee.

This research was conducted as a part of joint research by the Meiji University International Institute for Materials with Life Functions and Meiji Renewable Energy Laboratory .
