Figure 6: Reduction of H2O2mediated oxidative stress by PGA@MNPs. (A) Observed resistance of the cells to morphological changes induced by free GA, PGA@MNPs, or H2O2during the observation period of 2 h. (B) The changes in mean fluorescence intensity (MFI) of DCF measured in the population of morphologically viable cells in function of dosing of H2O2, free GA and PGA@MNPs.
