Nanotechnology innovation safety aspects - the case of graphene

Nanowerk.com - 16 октября, 2017 - 15:40
Currently, most graphene-based innovations are not yet at the level of large-scale commercial production. But public and private investments into graphene and its applications in products are large and whichever production methods eventually turn out to be successful, exposure to humans or the environment somewhere along the value chain or life-cycle of the material or product should be anticipated timely. A new review paper offers suggestions on how potential nanospecific safety issues can be addressed, by who and at what stage of the innovation process.
