Frequently asked questions
Actions of ultrafine particles (UFP) on the body: nanomaterials (NM)

Where can I find toxicity and ecotoxicity tests?

Standardized tests published by international organizations such as the OECD can be used, provided that the mode of administration is adapted to the specific characteristics of nanomaterials.

What parameters do you need to control for your studies?

We need to know all the physico-chemical parameters that differentiate nanomaterials from macro- and micrometer-sized powdery matter.

• Parameters such as the agglomeration and aggregation of nanoparticles can change the size of the particles tested.

• Biological contamination by Gram-negative bacteria can increase the inflammatory effect.

• Interaction with proteins forming a protective layer around nanoparticles,...
