    Abstract

    Titanate nanofibers were prepared on titanium mesh by alkali-heat treatment, and calcium phosphate coating was fabricated on the porous titanate nanofibers by electrochemical deposition technology. Then hBMP-2 was introduced into the coating by different methods to improve its osteointegration and bioactivity. Three kinds of composite coatings modified by hBMP-2 were prepared (TmhB, TmHedhB and TmHhBed). Surface morphology, chemical composition, phase composition and hBMP-2 amounts and hBMP-2 release performance of the composite coatings were characterized by SEM, ATR-FTIR, XRD, and hBMP-2 ELISA kit, respectively. Results showed that all of the coatings display porous fiber structure, calcium phosphate phase in TmHedhB and TmHhBed samples was hydroxyapatite (HA), and bead-like HA particles formed on the surface of titanate nanofibers. Protein adsorption experiments showed that introduction of bead-like HA phase increased the hBMP-2 adsorption on the composite coatings, and composite coatings prepared by electrochemical co-deposition technique further enhanced hBMP-2 adsorption up to 886 ng/mg, which were supported hBMP-2 sustained release within 6-48 h.
