Figure 5From: Metallacarboranes for proton therapy using research accelerators: a pilot studyViability of U87 cells after proton irradiation. Ratios between irradiated and non-irradiated cells for controls and for those cells treated with FeC and I2FeC compounds are plotted. Significant differences to non-irradiated cells (*) are indicated in the graph (\(p<0.05\))Back to article page
