摘　　要：生物体内有机基质指导矿物晶体的成核、生长和聚集,使得生物矿物具有特定的形貌、取向和组装方式,从而产生特殊的功能。本文从有机基质与矿物的晶格匹配、立体化学互补和空间定位、静电作用和电荷匹配,以及分子间弱相互作用力等方面综述了生物矿化过程中所涉及的机理,并讨论了生物矿物的分布和特性、生物矿化过程中的有机基质、生物矿化的过程和类型。The controlled nucleation, growth and aggregation of biominerals in organism under the mediation of organic matrices lead to specific morphology, orientation and assemblies of the biominerals, and consequently give them special functions. The mechanisms involved in biomineralization are reviewed in this paper from the points of lattice matching between organic matrices and biominerals, stereochemistry complementarity and spatial localization, electrostatic effect and charge matching, and intermolecular weak interactions. Moreover, the distribution and characteristics of biominerals, organic matrices in biominerals, the processes and types of biomineralization are discussed.
