Nanoparticles (NP) are novel materials being used increasingly in a range of fields, including in medicine. When NP enter the blood stream, they often interact with proteins to form a "corona", which may change the properties and function of the nanoparticle; it is also thought that formation of the corona is related to toxic effects of nanoparticles. However, how proteins bind to NP and how exactly this protein-inorganic interaction occurs remains largely unknown; consequently, any prediction of corona formation and of potential toxicity of NP remains difficult. In this project, we aim to study the interaction at the biological-inorganic interface, in specific model proteins binding to silica and gold NP of defined size and surface chemistry. Using a reiterative approach combining experiment and computation, hypotheses generated compitationally will be tested experimentally using recombinant protein mutants designed to probe potential interaction sites.
