Nanos and Health
Nanos and health
In many fields (cosmetics, food, textiles, construction, medicine, etc.), manufactured nanomaterials are increasingly used for their specific properties (anti-bacterial properties, modification of appearance, color, texture, etc.). However, these same “desirable” properties can lead to undesirable effects on health, where many uncertainties and concerns remain: due to their increased reactivity, nanomaterials are indeed likely to cause toxicity and potentially stronger inflammatory effects than “conventional” materials of the same chemical nature.
The studies carried out so far are mainly in vitro while the in vivo studies are mainly in animals with toxic effects on the heart, liver, spleen, stomach and kidneys.
The results are not all necessarily applicable to humans but still provide valuable information on the potential adverse health effects.
According to a scientific paper published in 2021, the nanoparticles with the greatest risk to human health are nano-TiO2 (titanium dioxide), silver nanoparticles, silicon dioxide (silica) and carbon nanotubes.

Upcoming Nano Agenda
- Fête de la Science open day at the Laboratoire National de Métrologie et d’Essais (LNE)
- “Tiny, powerful, fascinating… Nanomaterials, and nanoparticles in particular, are at the heart of many innovations – but also of big questions. How do we observe them? How are they measured? What challenges do they pose for science and society? Come and explore a world that the eye cannot see… but which is already shaping the world of tomorrow”.
- Website: www.lne.fr/fr/evenements/fete-science-lne-ouvre-ses-portes
- 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.
