Genotoxicity of silver nanoparticles evaluated using the Ames test and in vitro micronucleus assay

► Genotoxicity of AgNPs was assessed using the Ames test and micronucleus assay. ► The AgNPs are negative in the Ames test and positive in the micronucleus assay. ► The micronucleus assay is more appropriate than the Ames test for the evaluation.
