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
- 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.

- 7th Environmental nanotechology Gordon Research Conference (GRC)
- Chairs: Peter Vikeslan and Denise Mitrano
- Date: June 1-6, 2025
- Website: https://www.grc.org/environmental-nanotechnology-conference/2025/
- Workshop on risk assessment of nanomaterials and materials containing small/nanoparticles in the food and feed chain
- Organizer: EFSA
- This workshop will present the proposed strategy for updating the EFSA Nano Guidance documents, aiming to merge them into a single guidance on risk assessment for nanomaterials and small/nanoparticles in the food and feed chain.
The event will provide an open platform for discussing key issues, approaches to addressing them, and ensuring the guidance reflects the latest scientific knowledge. Stakeholders will be encouraged to share experiences and engage with regulators, helping shape the updated guidance. - Website: www.efsa.europa.eu/en/events/workshop-risk-assessment-nanomaterials-and-materials-containing-smallnanoparticles-food-and
