Photofunctional Co-Cr Alloy Generating Reactive Oxygen Species for Photodynamic Applications

Figure 4

Reaction time dependent UV-Vis spectra of DPBF in the presence of the photofunctional Co-Cr alloy plate in EtOH solution with a 510 nm laser irradiation. The inset represents the ratio between the after decomposition reaction O.D. (𝐶) and the initial O.D. (𝐶₀) of DPBF as function of irradiation time: (a) DPBF only under the light, (b) DPBF with the photofunctional Co-Cr alloy plate in the dark condition, (c) DPBF with the photofunctional Co-Cr alloy plate under the light.
