Abstract

Abstract : The properties of orally ingested nanoparticles can be influenced by the conditions prevailing in the digestive tract. The influence of the pH value on the fate of metal oxide nanoparticles was demonstrated using a simplified digestion approach. Abstract : The physicochemical properties of orally ingested metal nanoparticles can be influenced by the conditions prevailing in the digestive tract. In our work, we demonstrate the strong influence of the pH value on particle fate using a simplified digestion approach to analyze magnesium oxide, copper oxide and zinc oxide nanoparticles and show why a separate consideration of the digestion parameters is necessary.
