a) Schematic illustration of formation and self‐degradation by Fenton's reaction of Sgc8‐NFs‐Fc carrier. b) SEM images of developed systems with diverse sizes: (A) 1000 nm Sgc8‐NFs, (B) 200 nm, (C) 100 nm, (D) 50 nm Sgc8‐NFs‐Fc and (E) Different sizes of Sgc8‐NFs‐Fc. c) Distribution of DOX in cells treated with H₂O₂ stimulating PMA than MCF‐7 cells after incubation with (A) Sgc8‐NFs‐Fc/DOX and (B) Sgc8‐NFs3h/DOX. The treatment time of PMA was 60 min. Reproduced with permission from.^{[ 107 ]} Copyright 2019, American Chemical Society. PAM: Phorbol‐12‐myristate‐13‐ acetate; NAC: N‐acetylcysteine.
