Fe3O4 MNPs carrier affect the uptake of siBIRC5 and AS-ODN by cells. A Delivery of siBIRC5 and AS-ODN into A549 and H460 cells by visualization of FAM-labeled siBIRC5 and AS-ODN by Fe3O4 MNPs under magnetic field. Lipofectamine 3000 (lipid) was used as a positive control for siBIRC5 and AS-ODN transfection (scale bars = 100 µm). B Fluorescence intensity of A549 cell lysates analyzed by fluorescence spectroscopy (λex: 494 nm; λem: 519 nm). C Fluorescence intensity of H460 cell lysates analyzed by fluorescence spectroscopy (λex: 494 nm; λem: 519 nm). * indicates p < 0.05
