Fate, uptake and gut toxicity of two colloidal silver products in mice: how micro X-ray fluorescence, micro X-ray absorption spectroscopy and near-infrared spectroscopy provide new insights in food nanotoxicology

Silver biodistribution and gut toxicity of two different colloidal silver products were evaluated in mice after oral exposure. Biophysics-based methodologies provided novel insights into (nano)silver uptake, fate and toxicological effects.
