ROS formation induced by CPT-11-loaded DSPE-PEG2000 targeting EGFR liposome. A Fluorescent intensity of CPT-11, CPT-11-Lipo, EGFR-Lipo-CPT-11 and control cells. Original magnification 100×. scale bar: 100 µm. B The scale bar representation of the fluorescent intensity. C Mean fluorescent intensity (MFI) of CPT-11, CPT-11-Lipo, EGFR-Lipo-CPT-11 and control cells; D intracellular ROS level of CPT-11, CPT-11-Lipo, EGFR-Lipo-CPT-11 and control cells (**p < 0.01, ***p < 0.001)
