Surface characterization of different titanium surfaces. (A) SEM images of surface morphologies of cp-Ti, Ti-NW, and Ti-NW-Zn. Upper panel: ×5000 magnification. Lower panel: ×50000 magnification; (B) XPS wide scan spectra analysis of cp-Ti and Ti-NW-Zn surfaces; (C) XPS high-resolution spectra analysis of Zn 2p; (D) contact angles of cp-Ti, Ti-NW, and Ti-NW-Zn surfaces. Results were presented as mean ± SD (*p < 0.05, **p < 0.01; N = 3); (E) concentrations of Zn ion released from Ti-NW-Zn samples into PBS after 4 h and 1, 4, and 7 days; N = 3.
