Fig. 9From: Impact of nanosilver on various DNA lesions and HPRT gene mutations – effects of charge and surface coatingCytotoxicity effect measured by Plating efficiency (PE) assay. Bars represent cytotoxicity relative to 100 % of untreated cells, expressed as mean ± SD of three independent experiments. The data are expressed as mean ± SD of three independent experiments. P values indicate statistically significant results; *p < 0.05; **p < 0.01; ***p < 0.001. Cytotoxic effect was not observed for any of stabilizers tested (data not shown)Back to article page
