Nanoparticles Could Disrupt Immune Cell Function | Chemical & Engineering News | Nanotechnology & Health | Scoop.it

"A new study suggests there’s more to nanoparticle toxicology than cell life and death. Although immune cells treated with iron oxide particles appeared healthy in standard toxicology tests, they struggled to perform one of their key jobs: engulfing pathogenic bacteria (ACS Nano 2013, DOI: 10.1021/nn402145t). The researchers wonder if exposure to significant levels of the nanoparticles could lead to dysfunction in people’s immune systems."
