Figure 4. — Transfection efficiency of PEI-Fe₃O₄/siRNA complexes. (A) Fluorescence microscopy image of LX-2 cells transfected with PEI-Fe₃O₄/siRNA complexes (original magnification, ×200). Red fluorescence indicates Cy3-labeled siRNA, while blue fluorescence represents DAPI-stained nuclei. The scale bar represents 100 µm. (B) Transfection efficiency (percentage of cells transfected) of LX-2 cells transfected with PEI-Fe₃O₄/siRNA complexes and Lipo 2000/siRNA. PEI-Fe₃O₄, polyethyleneimine-functionalized magnetic iron oxide; siRNA, small interfering RNA; cy3, Cyanine 3; Lipo 2000, Lipofectamine 2000.
