The novel properties of nanomaterials can lead to new mechanisms of biological interactions. We aim to understand how nanomaterials interact with biological systems and to identify how changes in the physicochemical properties of nanomaterials can influence their cellular reactivity, intracellular fate, and potential toxicity. This fundamental understanding is then used to design safer nanomaterials or to tailor the unique biological interactions of nanomaterials for enhanced environmental, agricultural, or biomedical applications.
