Figure 7: The cytotoxicity of H2O2 to (a) C6 and (b) LoVo cell lines at various concentrations in PBS (pH = 7.4); (c) the cytotoxicity of a diversity of POMs to C6 cell lines without H2O2. The cytotoxicity of a diversity of POMs to (d) C6 cells and (e) LoVo cells in the presence of 0.2 μM H2O2 or not, control means only H2O2 treated. All concentrations of POMs were 20 μg/mL, Rubrene 0.3 μg/mL, and TPP 2 μg/mL. Error bars indicate standard deviations from ≥3 measurements.
