摘要：
One specie of Pectinidae with a crossed-lamellar structure and one of Plicata with a nacreous structure were selected as the target materials in this paper. The growth of bone-like apatite on the surfaces of these two kinds of microstructures by a pre-treatment and an in vitro bioactivity assessment was investigated. The apatites were deposited more compactly and more quickly on the surface of crossed-lamellar structure in the preliminary stage of immersion in PBS, as well as in SBF. However, these two kinds of microstructures exhibit identically an excellent bioactivity after a subsequently long-term in vitro mineralization process in SBF. Therefore, in contrast to nacreous structure the crossed-lamellar structure can promote the deposition of the apatites no matter in a short term or in a long term. © 2023 Chinese Journal of Materials Research.
