Abstract
Hydroxyapatite is ideal as the main mineral of bones and teeth. Artificially synthesized hydroxyapatite has been extensively used in a variety of applications, such as biomaterials, ion exchangers, adsorbents, and catalysts by exploiting its biocompatibility and adsorbability with many compounds. In this presentation, the conditions for the preparation of transparent block consisting of low crystallized hydroxyapatite and the cell adhesion property of the block will be reported. The hydroxyapatite transparent block should be useful for cell culture substrates because the cells adhered on the hydroxyapatite transparent block can be directly observed with an optical microscope without any pretreatments.
