Calcium phosphate quantification on titanium disks after 1-day or 5-day immersion in SBF.

Notes: As-made and photofunctionalized titanium disks were compared. (A) XRD spectra and a histogram quantifying the intensity of apatite-specific signal at 32° (2θ angle). The XRD analysis as performed on three independent titanium samples for each group (n=3). (B) The amount of calcium phosphate measured by chemical detection. *P<0.05, **P<0.001, significant difference between as-made and photofunctionalized titanium.

Abbreviations: SBF, simulated body fluid; XRD, X-ray diffraction.
