Green emission and Laser scanning confocal microscope images. (a) Green emission of the internalized Arg-Eu-HAP into the cells under fluorescence microscopy. Arg-Eu-HAP (green) were evident in the cytoplasm, nucleus were counterstained with DAPI dye (blue). Representative images of four different experiments are shown (magnification ×40). (b) Laser scanning confocal microscope images (magnification ×60, insert magnification ×252). No fluorescent light in the control cells can be detected.
