文摘

Silver and AgNPs speciation during human gastrointestinal digestion was performed. AgNPs transformation occurs during salivary, gastric and intestinal digestions. AgNPs and dissolved silver coexist in the digestion fluids. 13% of the AgNPs spiked meat chicken reach the intestinal wall. The proposed method allows accurate AgNPs sizing and quantification in complex extracts.
