Jun 24, 2021 · Nanomaterials consist of nanoparticles (NPs) , which are particles, with at least two dimensions between about 1 and 100 nm (Klaine et al. 2008). Though, a single globally recognized definition for nanomaterials does not present. Diverse groups have dissimilarities in belief in defining nanomaterials (Boverhof et al. 2015). To be classified as ...

What is the definition of nanomaterial? Read the insightful article published on Nature Nanotechonoly by Kristen Rasmussen, Juan Riego Sintes and Hubert Rauscher titled "How nanoparticles are counted in global regulatory nanomaterial definitions".
Nanotechnology can be defined as the systematic study of materials that have properties critically dependant on length scales on the order of nanometers. Such novel and improved properties make nanoscale materials promising candidates for a wide range of applications that are expected to improve our lifestyles.
As the regulation focuses on exposure and risk of marketed products, its nanomaterial definition explicitly states that where nanomaterials are used in a product, the risk to human health, animal health and the environment must be assessed separately, covering both active and non-active substances.
