Fluorescence images of green magnetic nanoparticles in DiI- and DAPI-labelled PK-15 cells and enlarged images. (a to e) Fluorescence images of green magnetic nanoparticles in PK-15 cells labelled with membrane-specific red fluorescent dye DiI and nucleus-specific blue fluorescent dye DAPI. (f) Enlarged merged fluorescence image in order to observe the location of NPs clearer.
