Abstract

Different methods for the functionalization of carbonate hydroxyapatite granules with free amine groups by reaction with (3-aminopropyl)triethoxysilane (APTES) have been compared in order to improve the potential for tethering of bioactive molecules to bioceramics. The combined use of tetraethoxyorthosilicate and APTES with acid catalysis resulted in an evident increase in amine surface grafting.

摘要

不同的方法,用于通过与(3-氨丙基)三乙氧基硅烷(APTES)反应使碳酸羟基磷灰石颗粒官能化,以游离胺基团,以提高生物活性分子与生物陶瓷的连接潜力。四乙氧基正硅酸酯和 APTES 与酸催化的联合使用导致胺表面接枝的明显增加。
