Figure 4From: Cytotoxic effects and the mechanism of three types of magnetic nanoparticles on human hepatoma BEL-7402 cells MNPs-induced loss of MMP. The MMP was measured by flow cytometry using JC-1 dye. Exposure of BEL-7402 cells to three types of MNPs (0.05 and 1 mg/mL) for 24 h decreased the MMP. *P < 0.05 vs. control; **P < 0.01 vs. control.Back to article page
