February 22/Islamabad, Pakistan/International News Network -- Billions of engineered nanoparticles in foods and pharmaceuticals are ingested by humans daily, and new Cornell research warns they may be more harmful to health than previously thought.
A research collaboration led by Michael Shuler, a professor of Chemical Engineering and chair of Biomedical Engineering at Cornell University, studied how large doses of polystyrene nanoparticles -- a common, FDA-approved substance found in substances ranging from food additives to vitamins -- affected how well chickens absorbed iron, an essential nutrient, into their cells.
