Figure 12: Chelating activity of Fe2+ ions by free PLGA nanoparticles (aI, bI), free quercetin 20 μM (aII), free quercetin 100 μM (aIII), encapsulated quercetin 20 μM (aIV), encapsulated quercetin 100 μM (aV), free catechin 20 μM (bII), free catechin 100 μM (bIII), encapsulated catechin 20 μM (bIV), and encapsulated catechin 10 μM (bV). Different letters represent significantly difference ( 𝑃 < 0 . 0 5 ) between treatments at one specific time of experimentation (0.25, 4, 12, 24, and 32 h). Results are represented by the mean ± SE.
