Fig. 8. CLSM-images of HepG2 cells incubated with PMSNs@DOX and PMSNs@DOX@FA; for each series, images from left to right can be classified to the cells in the nuclei of cells (blue, being stained by DAPI), DOX fluorescence in cells (red), and the merged images of DAPI (blue) and DOX (red), respectively. Scale bar is 100 μm.
