Abstract excerpt

The mutagenic effect of multi-walled carbon nanotubes (MWCNTs) characterised by small surface/volume ratio, high diameter and less than 0.1% of metal contaminants was evaluated by the bacterial reverse mutation assay (Ames test) on Salmonella typhimurium TA 98 and TA 100 strains, and on Escherichia coli WP2uvrA strain, in presence and in absence of the metabolic activation system S9. A preliminary cytotoxicity...
