Our new veillenanos.fr website is online!
The new website https://veillenanos.fr of our association AVICENN is now online.
After a long wait, we have now a modernized website to share information on nanos, their risks, their regulation and the challenges that remain to be met for more transparency and vigilance.
This vast redesign project has kept us very busy for more than a year and a half and we are proud to present it to you today. It brings on a single interface, the information on nanos that was compiled on veillenanos.fr, as well as the presentation of our association previously available on a separate site, avicenn.fr.
More ergonomic and functional, the new site offers a greater ease of navigation and access to the various contents, now filterable and adapted to smartphones.
We created the general design, the web agency Digital Cover brought us its expertise and precious help to build the structure and pages. Sophie Raynal @pretemoitesyeux.fr drew the banner and we imported (and “refreshed” as we did) our most recent contents with the help of some kindhearted reviewers who volunteered to read, complete or update some of the files.
If we can’t credit everyone here, we would like to collectively thank all those who supported us as well as our funders (the Foundation for the Progress of Humankind, Un monde par tous, TOP Fund and the Ministry of Ecological Transition) without whom this massive work would not have been possible.
We hope you will enjoy this new site. Do not hesitate to send us your comments either on the form and/or on the content.
We still have some adjustments to make to the layout, old content to import or update… and new content to build. Because this site is destined to be, by its very nature, in constant evolution, you are invited to bring your stone to the edifice, to improve this collective work so that it becomes even more complete and clear.
Feel free to share with us information, publications, analyses, images (and associated rights), events, questions and/or recommendations by writing to us at contact@veillenanos.fr or via our “contact” page or the social networks: twitter, facebook and linkedin.
As you read through the content on this new site, it becomes increasingly clear how urgent it is to share information on nanos, so that only those with a positive benefit/risk ratio are authorized.

Enjoy your visit and see you soon.
PS: Next steps? Re-launch the newsletters with the new design and complete the English version of the site.

Upcoming Nano Agenda


- Webinar presenting the example guide produced by NanoMesureFrance, to illustrate the difficulties encountered in dimensional analysis of particles by electron and atomic force microscopy.
- Organizers: Eurotox
- Speaker: Carola Voss (Helmholtz Zentrum München)
- Registration form

- MOOC from April 28 to June 22, 2025
- Public who has carried out two or more years of scientific studies at university, as well as professionals or the self-educated who want to discover, learn more or acquire specific knowledge in some area of nanoscience.
- Organizer: Paris Saclay University
- Course paln:
- Theme 1: Introduction to nanoscience and nanotechnology – Let’s lay the foundations and discover the key concepts of this field.
- Theme 2: How can you “see” and fabricate nano-objects? We will discover what tools are used to observe matter at these scales and what techniques the scientist can use to make objects that are only a few billionths of a meter in size.
- Theme 3: Nanochemistry – From carbon to porous solids and nanoparticle synthesis; applications of the field.
- Theme 4: Nanophysics – Quantum effects and nanoelectronic devices; optical nanostructures: the confinement of light and emission; nanosensors; applications of the field.
- Theme 5: Nanobiology, Nanomedicine, Micro-nanofluidics – The study and manipulation of molecules; treating diseases with nanomedicine; the on-chip manipulation of liquids for medical diagnosis; applications of the field.
- Theme 6: Nanoscience and Society: Are Nanotechnologies dangerous? Societal, health and environmental issues.
- Website: www.fun-mooc.fr/en/courses/understanding-nanosciences

- E-learning program: awareness-raising for personnel who come into contact with nanomaterials during research, formulation, production, maintenance, cleaning, upkeep, etc., as well as safety coordinators or engineers, facility managers, heads of laboratories where nanoparticles are handled.
- Organizers: INSTN Grenoble (CEA)
- On the program:
- 1 – Introduction, definition and characteristics of nanomaterials
- 2 – Toxicity of nanomaterials: the state of knowledge
- 3 – Metrology and characterization of nanomaterials
- 4 – Prevention and protection against nanomaterials in the workplace
- 5 – Quiz: assessment of learning outcomes
- The 2-hour course can be viewed for one month from the date of registration.
