One of the many questions in the human risk assessment of metallic engineered nanomaterials (ENM) such as silver ENM is whether these ENM dissolve in the gastrointestinal (GI) system or are absorbed and translocated to organs and tissues as intact nanoparticles. It is difficult to elucidate this question as in situ measurement of silver ENM is still hampered by technical difficulties, but also because silver nanoparticles can be formed in vivo after exposure to silver salts. To tackle these difficulties, we compared the tissue distribution of orally administered silver ENM with the tissue d…
