摘要
This study is aimed at the development of a method to fabricate porous spherical hydroxyapatite (HA)-fluorapatite (FA) granules. The method to produce porous granules is based on liquid immiscibility effect. A suspension of HA-FA powder mixtures in aqueous solution of gelatin and oil as a dispersion media were used. By stirring the mixtures of these immiscible liquids, granules of 50-200 mm diameter can easily be produced. The granules were characterized with respect to their microstructure, phase composition and specific area. In vitro testing of human plasma protein adsorption onto the granules of HA and fluorhydroxyapatite were performed. No kind of difference in the dynamic protein adsorption between pure HA and the HA up to 10 wt% FA materials has been revealed. (C) 2003 Elsevier Ltd. All rights reserved.
