CLSM images of calcein-AM-stained HeLa cells (green fluorescence) showing the photodynamic effect of the encapsulated forms of Cholosens (red fluorescence): (a,b) control cells incubated without PMC; (c–f) cells incubated with [DS/PArg]4 microcapsules ((c,d) intact, (e,f) heated) added at the concentration of three capsules/cell (37 °C, 24 h) before and after light irradiation at 670 nm for 60 s, respectively. White arrows point to the individual cells, which were exposed to light irradiation. The capsules were added in the amount of three capsules/cell.
