Isolated in 2004 by Andre Geim and Konstantin Novoselov, graphene is an exceptional nanomaterial, described as a "material of the 21st century" (European Graphene Flagship project with a budget of one billion euros over 10 years). It is very light, impermeable, chemically inert, transparent, flexible yet extremely resistant and an excellent conductor of heat and electricity,

News regularly reminds us that the development of nanomaterials is not without health and environmental risks. Nevertheless, some nanomaterials have interesting applications for society, for example in the manufacture of resistant materials, energy storage, depollution or medicine. How to decide between risks

For ages we have dreamt of small objects circulating in our bodies, on the lookout for the slightest disturbance, to eradicate it with a magical ray of light. Hollywood has made them blockbuster movies, science fiction writers have enjoyed them. But today, reality seems to have overtaken fiction. Everywhere

Nanomaterials and nanoproducts are widely used in automotive transportation. Firstly for the manufacture of tyres (carbon black, silica, nanostructured materials), for the reinforcement of mechanical parts and joints by means of nanocomposites, but also for the lightening of chassis and passenger compartments, or to increase the autonomy of batteries,

Various nanomaterials, including organic nanocapsules, nano-silver, titanium dioxide and amorphous silica, are used by the food industry as food and packaging components. Consumption of certain products, such as confectionery, can lead to significant digestive exposures to nanotitanium. Does this result in toxicity

Filter membranes with micropores tend to spread to provide drinking water or to desalinate sea water. Nanostructured filter materials are being considered to complement these devices; for example, to filter pesticide and drug residues or to clean up water tables. The expected efficiency gain

Plus de 1 600 produits de consommation contenant des nanomatériaux ou nanotechnologies ont été commercialisés à l’échelle mondiale, près de 500 sur le marché européen. Le nanomatériau le plus utilisé est le nano-argent, suivi du dioxyde de titane et des nanotubes de carbone. Pour le consommateur, le moyen le plus
