Fig. 1 Characterization of particles and scaffold. Characterization of particles and scaffold. (A) XRD patterns of n-HA, μ-HA, and n-TiO2 particles. The standard spectra of HA, antase TiO2, and rutile TiO2 are given below. a.u., arbitrary units. (B) Representative TEM image of n-HA, SEM image of μ-HA, and TEM image of n-TiO2. (C) SEM images of 3D-printed porous titanium scaffold subjected to acid-alkali treatment, coated with n-HA and surface/cross-sectional alignment of n-HA with EDS confirmation. The dotted yellow line indicates the interface between n-HA coating and scaffold. The yellow arrow marks the average thickness of n-HA layer. Ca/P indicates atomic molar ratio of the selected region. (D) Weight change of particles released from n-HA/scaffolds immersed in tris-HCl solution for 7 days. Error bars represent SD. n = 3 replicates. (E) Representative TEM image of the released n-HA particles. (F) XRD pattern of the released n-HA particles. The asterisk indicates characteristic peaks of HA. Kun Zhang et al.
