Figure 8From: Evaluation of cytotoxic, genotoxic and inflammatory responses of nanoparticles from photocopiers in three human cell lines Percentage DNA damage studied using comet assay in all three cell types. Percent of DNA in the tail (tail DNA%) was used as a marker of DNA damage in all three cell types (A) THP-1 cell line, (B) nasal epithelial cells and (C) small airway epithelial cells. All values are depicted as mean± SE.Back to article page
