The Nanotechnology Information Library (NIL)
NIOSH is working with its national and international partners to develop a web-based Nanoparticle Information Library (NIL). The goal of the NIL is to help occupational health professionals, industrial users, worker groups, and researchers organize and share information on nanomaterials, including their health and safety-associated properties.
