First, a nanomaterial is a material with special properties due to its size and nanometric structure. Intentionally manufactured, nanomaterials are characterized by one or more external dimensions, or internal structure, on a scale of 1 to 100 nm.
Actors in different sectors, classify your substances (nano or not?) allow you to improve or substitute your products by using nanomaterials and nanotechnologies (nanosensors, nanovectors, nanoparticles, nanocomposites, nanocatalysis…).
