Figure 6. Released amount of Ti (A) and Cu (B) from as-cast Ti-11.5Cu, BP-LPBF Ti-3Cu, and Ti-11.5Cu alloys into PBS and PBS + 10 g/L BSA + 30 mM H₂O₂ after 24 h at 37 °C. The released amount (µg/cm²) is normalized to the solution volume and the exposed surface area and shown on a logarithmic scale because of the large difference between the two solutions. Corresponding aqueous concentrations (µg/L) of Ti and Cu in PBS (C) and PBS + 10 g/L BSA + 30 mM H₂O₂ (D). All shown values are blank- and dilution factor-corrected average values between triplicate samples, with the error bars representing the standard deviations. *P < 0.05; **P < 0.01; ***P < 0.001.
