1. What is a nanomaterial?

1.1 Current definitions

The most generic definition is that of the International Organization for Standardization, which defines a nanomaterial as a material with an external dimension on the length scale extending from approximately 1 nm to 100 nm, or with an internal structure or surface structure on the nanometric scale.

Currently, several definitions of nanoscale materials (often referred to as nanomaterials and sometimes nanoscale substances) coexist, defined by different authorities and with different fields of application in Europe (tables 1 and 2 ).
