Cell viability and proliferation assessment of AgNPs in NIH3T3 cells. (A) Viability of NIH3T3 cells was determined 24 h after exposure to different concentrations of AgNPs using the CCK-8 assay. (B) Cell proliferation assay was performed using the BrdU cell proliferation assay. The results are expressed as the mean ± standard deviation of three independent experiments. There was a significant difference in the ratio for AgNP-treated cells compared to untreated cells according to a Student’s t-test (* p < 0.05).
