中文摘要	In the present study, Antheraea pernyi silk fibroin (Ap-SF) is employed to regulate the mineralization of hydroxyapatite (HAp) nanocrystals. Calcium phosphate crystals precipitate in the aqueous solution of regenerated Ap-SF at pH 7.4 and room temperature. The samples are charaterized with X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and scanning electron microscopy (SEM). Based on the XRD results, the inorganic phase in the mineralized Ap-SF composites is HAp as small particles with low crystallinity. The FTIR analysis reveals that the HAp crystals are carbonate-substituted HAp and compounded with Ap-SF. The TEM images show mineralized nanofibrils in the composites as rod-like shapes 4-5mn in diameter. Electron diffraction (SAED) patterns of selected areas of the composites exhibit polycrystalline rings that are ascribed to HAp. SEM images show mineralized Ap-SF composites with several mineralized rods 49-74nm in diameter.
