This property has led to advances in a wide range of industries, but it can also confer toxicity. Size measurements are the main way NPs are identified but a lack of standardised methods for identifying ones with complex shapes has hindered evaluation of their potential harm.

In this phase, it is important to build trust between the individual partners in the product value chain. This requires trustworthy statements based on reliable and reproducible material characterisation. The first steps have been taken to measure graphene and other related 2D materials (GR2Ms) under well-defined conditions. Measurands and protocols for key methods were made available for this purpose. But there are still some challenges to overcome such as (i) reference materials, (ii) reference data, (iii) reproducibility throughout the workflow, (iv) credible structure-activity relationships, bringing the standards to (v) the factory floor and to (vi) real-word products. In addition, 2D materials beyond graphene should also be considered exploiting the knowledge gained from the characterisation of GR2M.
