Multi-hierarchical profiling the structure-activity relationships of engineered nanomaterials at nano-bio interfaces.

ABSTRACT: Increasing concerns over the possible risks of nanotechnology necessitates breakthroughs in structure-activity relationship (SAR) analyses of engineered nanomaterials (ENMs) at nano-bio interfaces. However, current nano-SARs are often based on univariate assessments and fail to provide tiered views on ENM-induced bio-effects. Here we report a multi-hierarchical nano-SAR assessment for a representative ENM, Fe₂O₃, by metabolomics and proteomics analyses. The established nano-SAR profile allows the visualizing of the contributions of seven basic properties of Fe₂O₃ to its diverse bio-effects. For instance, although surface reactivity is responsible for Fe₂O₃-induced cell migration, the inflammatory effects of Fe₂O
