Supporting the responsible use of nanomaterials
Nanosafety Platform general presentation
Nanoparticle: nano-object with all external dimensions in the nanoscale where the lengthsof the longest and the shortest axes of the nano-object do not differ significantly.
Nano-object: discrete piece of material with one, two or three external dimensions in the nanoscale.
NOAA: Nano-Objects and their Aggregates and Agglomerates.
The European Commission's definition, which distinguishes nanomaterials from non-nanomaterials, marks a first step toward developing nanomaterials legislation. In October 2011 the European Commission issued a recommendation that should serve as a frame of reference in determining whether or not a material should be considered a nanomaterial for regulatory and policy purposes:
According to the European Commission, a nanomaterial is "a natural, incidental or manufactured material containing particles, in an unbound state or as an aggregate or as an agglomerate and where, for 50% or more of the particles in the number size distribution, one or more external dimensions is in the size range 1 nm-100 nm."
The European Commission's recommended definition is merely a first step toward regulating nanomaterials and is not currently legally binding. Further discussion will be required to establish a definitive, broadly-accepted definition.
The nanosmile program, which was set up under the EU NanoSafe2 program, aims to provide a deeper understanding of nanosafety issues.

CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
