The test battery recommended for NM assessment uses all in vitro
mammalian systems, without bacterial mutagenicity, without animals
unless there is clear evidence of animal-specific effects.

After describing what was wrong with the literature, we published 4
papers from HESI describing how genotoxicity assays should be conducted
using OECD credentialed assays altered for assessment of NM (Figure 4).
