Light-induced ROS formation indicated through triiodide production followed by absorption spectrometry. (a) A typical series of absorption spectra of MPCl + liposome sample during the photoreaction with increasing optical density (OD) due to increasing irradiation time (0–5 min). (b) Difference of the two respective absorption spectrum, namely the actual minus the initial one. Gray part marks the averaging range for Fig. 3, arrow shows the increasing irradiation time (1–5 min; irradiance: 500 klux).
