Hydroxyphenyl fluorescein (HPF) was purchased from Shanghai Maokang Bio. Co. (Shanghai, China).\u00a0HPF was used to detect the generation of \u2022OH. Typically, 1 mL BB NCs aqueous solution (80 \u00b5g mL -1 ) containing with HPF (1 \u00b5M) were irradiated by 650 nm laser (0.5 W cm-2 ), the fluorescence of HPF was detected after 15 min. HPF aqueous solution with laser served as control.<\/span><\/p>\n

Hydroxyphenyl fluorescein (HPF) was purchased from Shanghai Maokang Bio. Co. (Shanghai, China).\u00a0For detecting intracellular \u2022OH generation, treated B16F10 cells were rinsed and stained with specific \u2022OH probe HPF (10 \u03bcM in PBS) for 60 min, followed by rinsed with PBS and imaged using CLSM. To further confirm the Fe(II) consumption, after treatment with H2O2 (positive control), CA and HA@CA for 12 h, the cells were stained with a ferric ion probe, 3\u2032,6\u2032-bis (diethylamino)-2-(4-oxopent-2-en-2-ylamino) spiro (isoindoline-1,9\u2032-xanthen)-3-one (10 \u03bcM) at 37 \u00b0C for 30 min. Finally, the treated cells were rinsed with PBS and observed by CLSM.<\/span><\/p>\n

Hydroxyphenyl fluorescein (HPF) was supplied by Shanghai Mao Kang biotechnology Co., Ltd.\u00a0For evaluating the different types of ROS, DHE and HPF were selected as probes to assess the generation of intracellular \u2022O2- and \u2022OH, respectively. Briefly, HepG2 cells (5\u00d7105 cells per well) were seeded in a 6-well plate and incubated overnight. After that, Free SFB, MnMSN@SFB or FaPEG-MnMSN@SFB at different concentrations (10, 20, and 40 \u00b5g\/mL of SFB equivalent) were added and treated for 6 h. Cells were then stained with DHE (20 \u00b5M) for another 45 min. Eventually, fluorescence microscope was employed to observe the fluorescence of cells at the wavelength of 535 nm. Moreover, to assess the generation of intracellular \u2022OH, HepG2 cells (1\u00d7105 cells per well) were seeded into confocal dishes and incubated for 12 h. Then, Free SFB, MnMSN@SFB or FaPEG-MnMSN@SFB at different concentrations (10, 20, and 40 \u03bcg\/mL of SFB equivalent) were added, meanwhile HPF (10 \u00b5M) was added to capture generative intracellular \u2022OH, following by co-incubation for 6 h. Eventually, CLSM was used to observe the fluorescence of cells at 490 nm.<\/span><\/p>\n

Probe 20,70-Dichlorodihydrofluorescein diacetate (H2DCFDA), dihydroethidium (DHE), hydroxyphenyl fluorescein (HPF) are commonly used for ROS detection.\u00a0HPF was used at 10 mM in 0.2 M PBS buffer (pH 6.1) for 2 hours. Comparable results were obtained in experiments tested with all three dyes, providing confidence for the observed changes in ROS levels.<\/p>\n

Singlet oxygen sensor green (SOSG), dihydroethidium (DHE), 3\u2019-(4-hydroxyphenyl) fluorescein (HPF), Fetal bovine serum (FBS), Dulbecco\u2019s modified Eagle\u2019s medium (DMEM), Hoechst 33342 and 3-(4,5- dimethylthiozol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) were purchased from Shanghai Maokang Biotechnology Co.,Ltd.\u00a0 Hydroxyl radical (\u2022OH) was detected by fluorescence spectroscopy using hydroxyphenyl fluorescein (HPF), which reacts with \u2022OH to produce high fluorescence emission at 530 nm. HPF was dissolved in DMF to gain 5 mM HPF solution. Then, 20 \u03bcL HPF was added into the solution of 2 mL FBC or FBC nanogels. The fluorescence changes were detected after illumination with 750 nm laser, and the excitation wavelength was 490 nm.<\/p>\n
