ROS scavenging ability of GFeSNs in vitro. In vitro NRK-52E (a) and HEK293 (b) cell viability under different treatment conditions (n = 5). c NRK-52E cell viability under H2O2 treatment (0.3 and 0.5 mM) with or without GFeSN (5 and 10 μg/mL) pretreatment (n = 3). d Representative ROS staining (green fluorescence) of NRK-52E cells under different treatment conditions. Scale bar = 25 μm. e Representative Calcein AM/PI staining of NRK-52E cells under different treatment conditions. Scale bar = 25 μm. Error bars are mean ± SD (*p < 0.05, **p < 0.01 and ***p < 0.001)
