Figure 2From: Cytotoxic effects and the mechanism of three types of magnetic nanoparticles on human hepatoma BEL-7402 cells The viability of BEL-7402 Cells incubated with MNPs. Cells viability was determined by WST-1 assay after BEL-7402 cells were treated with MNPs (0.01, 0.05, 0.1, 0.5, 1, and 2 mg/mL) for 24 h. The percentage of viable cells was calculated as a ratio of absorbance at 490 nm of treated to control cells.Back to article page
