Fig. 10. The inactivation of S. aureus in suspensions after adding ZnTPP/D-g-PAAan and irradiating with 420 nm light as a function of the light irradiation dose. The blue downward-pointing triangles show the dependence without the addition of ZnTPP/D-g-PAAan, as a reference. Concentrations: D-g-PAAan: 0.08 g L⁻¹, 0.008 g L⁻¹, 0.0008 g L⁻¹; ZnTPP: 0.001 g L⁻¹. The light power was 0.1 J s⁻¹ and the irradiation dose was in the range of 3–18 J mL⁻¹ with increments of 3 J mL⁻¹. The experimental points are spline-interpolated for convenience.
