Effects on the worm's survival

The survival rate of treated worms was normalized to controls and plotted as a function of time (Figure 2) for samples containing 50, 100 and 200 ug/ml of MAPbI3 (top panels) or MASnI3 (bottom panels). Non-treated worms (blue line) exhibited a survival rate of 100% then started to decay after 6 days because the compartments were filled with worms and they suffered a space limitation. When worms were exposed to MAPbI3, the population began to die after 60 hours from the beginning of the experiment. The dead worms are recognized by immobile, stiff shapes. This trend was more pronounced with higher doses (green and red lines), especially at the highest dose where no living worm could be observed after 5 days of exposure. MASnI3 started interrupting the worms’ survival as early as 20 hours, also in a time and dose-dependent fashion. At 200 ug/ml, the population suffered extensively the exposure and perished after 60 hours.
