Enhanced Hydrophilicity and Protein Adsorption of Titanium Surface by Sodium Bicarbonate Solution

Figure 6

Survey spectra of untreated (a), NaHCO₃-treated (b), and rinsed (c) SLA specimens. (a) Titanium (Ti), oxygen (O), and carbon (C) were the main elements of untreated SLA specimens. From (b), sodium (Na) was detected as another main element on the tested specimens after NaHCO₃ treatment. Compared with (a), (c) does not reflect any significant differences in elemental composition.
