HARN report considers health risks of high aspect ratio nanomaterials in relation to asbestos

A UK consortium of scientists, led by the Institute of Occupational Medicine, Edinburgh, has published a key report examining whether high aspect ratio nanoparticles (HARN) should raise the same concerns as asbestos fibres. HARN includes materials such as carbon nanotubes (CNT) and metal nanowires.
