In the past, the two major biomineralization motifs, biosilicification and biocalcification, were considered as two discrete processes. However, there is increasing evidence of the existence of an inextricable relationship between biosilica and calcium-based biominerals.[1] The recent discovery of a unique silica–chitin–aragonite biocomposite in one genus of demosponges (Verongida) introduces a novel mechanism of multiphase hierarchical biomineralization.[2] Considerable effort has been devoted to the development of silica-/calcium-based organic–inorganic hybrids;[3–5] however, none of the techniques used could demonstrate the composite nature of their natural counterparts. Herein, we report a bottom-up, biomimetic biomineralization strategy that results in the intrafibrillar mineralization of collagen with hierarchically arranged silica–apatite multiphase minerals. The mineralization mechanism involves the precipitation and crystal growth of polymer-induced amorphous calcium phosphate precursors within the intrafibrillar spaces of hierarchically silicified collagen. Silicified-collagen-templated intrafibrillar apatite formation provides a model for the formation of multiphase-mineralized skeletons in invertebrates and also results in a biocomposite with increased fatigue resistance and resilience owing to the interpenetrating arrangement of amorphous silica, collagen, and crystalline apatite; the biocomposite also demonstrates enhanced bioactivity, biocompatibility, and potential for the correction of bone defects as a result of the presence of these multiphase components.[1, 6, 7]
