Gut Dysbiosis and Neurobehavioral Alterations in Rats Exposed to Silver Nanoparticles

open access: yes, 2017
Due to their antimicrobial properties, silver nanoparticles (AgNPs) are being used in non-edible and edible consumer products. It is not clear though if exposure to these chemicals can exert toxic effects on the host and gut microbiome.
