The AVICENN association

AVICENN is an association whose purpose is to monitor and provide civic information on the issues related to nanoscience and nanotechnology. We exercise a citizen’s watch, propose transversal and independent information on nanomaterials and act for more transparency and vigilance in the nano field.

We research, compile and analyze information on nanotechnology and disseminate it widely in order to promote understanding of the issues and controversies to as wide an audience as possible.  We use this website, veillenanos.fr, and related social networks: twitter, facebook, Linkedin as well as other media: books, comics, interviews, etc.
