(a) Viabilities of 4T1 cells treated with different nanoparticles; (b) CLSM images of ROS levels in 4Tl cells treated with different concentrations of Fe3+ in PP@BSA-TAFeIII NPs (cell nuclei was stained by Hoechst 33342); (c) TEM images of 4T1 cells treated with PP@BSA-TAFeIII NPs for different times; (d) CLSM images of 4T1 cells stained with Calcein-AM/PI (green fluorescence for live cells, red fluorescence for dead cells) after treatment with different concentrations of Fe3+ in PP@BSA-TAFeIII NPs and irradiation with 808 nm laser (1 W·cm-2) for 10 min
