In-vitro Fenton-like reaction of AA-Fe3O4@FeIII-TA: A time-dependent generation of FeII ions in PBS with different pH values using 1,10-phenanthrene colorimetric method. B Determination of •OH using MB colorimetric method in the presence of H2O2 under acidic conditions (pH 5). Data was represented as mean ± SD (n = 3). Means were compared using ANOVA, followed by the Tukey test for multiple comparisons, two-to-two. (*p ≤ 0.05, (ap > 0.05)
