Species Dependent Toxicity Comparison Outcome
Advanced Science, EarlyView.By quantitatively assessing and comparing toxicity responses across different animal species and material compositions, our data reveal that toxicity rankings among different materials may be reversed across species. ABSTRACT Toxicity comparison plays a crucial role in material selection across diverse application fields.
