Bioaccessibility and cellular transport study of silver and titanium dioxide nanoparticles from exposed seaweed and mussels using Caco-2 cells.

ABSTRACT: Bioavailability studies on pollution pre-concentrator organisms such as algae and mussels are necessary to ensure food safety, particularly in the case of nanomaterials whose industrial applications have increased in recent years. Thus, the bioaccessibility and the bioavailability of total Ag and Ti and AgNPs and TiO₂NPs from raw and cooked seaweed (Palmaria palmata and Ulva sp.) and cooked mussels (Mytilus edulis) exposed to 1.0 mg L^-1 of 15 nm PVP-AgNPs, 1.0 mg L^-1 of 25 nm citrate-TiO₂NPs, or 1.0 mg L^-1 5 nm citrate-TiO₂NPs, for 28 days, were evaluated. Samples were subjected to an in vitro process simulating human gastrointestinal digestion while cell transport from the intestinal lumen to the bloodstream was mimicked us
