Figure 1. Examples of mechanistic toxicological responses for major types of ENMs.
These include transition metal oxide nanomaterials, silica-based nanomaterials, carbon nanotubes, graphene and graphene oxide, high aspect ratio materials, and highly soluble metal and metal oxides, rare-earth oxides. Using ENM libraries, properties of the ENMs (bandgap, dissolution, surface reactivity, aspect ratio, transformation, etc.) could be linked to mechanism-based in vitro (oxidative stress, lysosomal damage, NLRP3 inflammasome activation, cell death, etc.) and in vivo (e.g., lung inflammation and fibrosis) toxicity in a predictive fashion.
