Fig. 8From: Physicochemical characterization and genotoxicity of the broad class of carbon nanotubes and nanofibers used or produced in U.S. facilitiesGenotoxicity assessments. a Cells with micronuclei were quantified and presented as percentage of total cells at treatments of 0.024 and 2.4 μg/ml. b Inference into double stranded DNA breaks were quantified via detection of γH2AX. Percentage change from DM is presented on the y-axis. *p < 0.05 represents significant change from controlBack to article page
