Nanos? What are we talking about?

“Nano” comes from the Greek “nannos” and means “dwarf”. The nanometric scale is that of the infinitely small: 1 nanometer (nm) = ^10-9 meter = 0.000 000 001 m = 1 billionth of a meter.

Atthe nano scale, materials display “extraordinary” properties compared to “classical” materials, of micro or macroscopic size. This is why they are used in many different domains: food, cosmetics, textiles, paints, electronics, etc.

→ “New properties” also mean, potentially, “new risks”. Hence the need for an effective citizen vigilance on these.

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.

VeilleNanos.fr

AVICENN’s VeilleNanos website provides information on nanos and the associated risks.

Addressing citizens’ concerns, the site provides comprehensive information based on reliable, verified and documented elements.

The independent and multidisciplinary information is accessible to a wide audience.
