Comparative Study of Antitumor Activity between Lipophilic Bismuth Nanoparticles (BisBAL NPs) and Chlorhexidine on Human Squamous Cell Carcinoma

Figure 3

Cell membrane permeability of tumoral cells was determined after exposition to BisBAL NP or chlorhexidine by calcein-AM assay and fluorescence microscopy. CAL-27 cells were treated with 0, 10, or 50 μM of BisBAL NP or 50 μM of CHX for 24 h. After exposition, cells were stained with calcein-AM and DAPI. Bar indicates 5 μm.
