Fluorescent nanoparticles present in Coca-Cola and Pepsi-Cola: physiochemical properties, cytotoxicity, biodistribution and digestion studies.

abstract：:Titanium dioxide nanoparticles (TiO2 NPs) have shown great adsorption capacity for arsenic (As); however, the potential impact of TiO2 NPs on the behavior and toxic responses of As remains largely unexplored. In the present study, we focused on the physicochemical interaction between TiO2 NPs and As(III) to clarify th...
