Dynamic Probing of Nanoparticle Stability In Vivo: A Liposomal Model Assessed Using In Situ Microdialysis and Optical Imaging
Figure 5
The HepG2 cells treated with DPPG liposomes containing 100 mM CF (surface charge ca. mV) showed no CF fluorescence in the cytoplasm, implicating that no cell uptake of liposomes took place during the 4h imaging course. The scale bar is 10 m.
