Equipex NanoID : Nanoparticle identification platform

Nanoparticle identification platform dedicated to safety issues

Duration : 2011 - 2019
Funding : 10,2 M€ (National Research Agency)
Coordinator : LCSN/LITEN (CEA Grenoble)
ISTerre team involved : Geochemistry
Contacts at ISTerre : Laurent Charlet, Géraldine Sarret
Partners :
  • CEREGE & LCP (CNRS-Aix-Marseille Université),
  • U 959 (INSERM),
  • LSA-CIME (ANSES)

The equipexNanoID is a national platform for the chemical identification and spatial location of nanomaterials and nanoparticles in complex solid, liquid and gaseous systems (soils, sediments, aquatic environments, organisms, organs, cells, organelles) for toxicology and ecotoxicology, in order to answer current questions on the risk associated with the presence of these nanomaterials and nanoparticles manufactured in the natural environment and in living organisms.

The equipment consists mainly of :

1. At LITEN : from a Transmission Electron Microscope coupled to microanalysis, equipped with a cryogenic mode, an FFF separation tool coupled to an ICP-MS (LITEN)

2. At LCP : a mass spectrometer for aerosols (Api-TOFMS)

3. At CEREGE : 3D X-ray imagers with resolutions of 50 nm and 2µm

4. A ISTerre : from a nanozetasizer to measure the size and zeta potential of particles in a liquid medium.
