Tooth enamel is composed of arrayed fluorapatite (FAP) or hydroxyapatite nanorods modified with Mg-rich amorphous layers. Although it known that Mg2+ plays an important role in the formation enamel, there limited research on regulatory synthesis enamel-like materials. Therefore, we focus behavior fabrication biomimetic mineralized structural In present study, adopt a bioprocess-inspired room-temperature mineralization technique to synthesize multilayered array columnar FAP/polymer nanocomposites controlled by (FPN-M). The results reveal presence induced compaction and unique amorphous-reinforced architecture. FPN-M exhibits excellent mechanical properties. hardness (2.42 ± 0.01 GPa) Young's modulus (81.5 0.6 as-prepared are comparable those its biological counterparts; furthermore, translucent. synthetic without control (FPN) 0.51 0.04 43.5 1.6 GPa, respectively. study demonstrates reliable for development advanced high-performance composite
