Nanodilems: In praise of constraints

At a time when a national debate is being invented in France, with new and multiple forms, everyone is wondering: how can we move from mistrust to trust? What signals, experiences and results can be used to meet a central expectation, that of feeling counted and of having an impact?

Graphene, the nanomaterial of the future?

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,

Candies and cakes filled with nanoparticles: danger?

/

Out of 18 sweet food products sold in stores, 100 % of the products contain nanoparticles, none of which are labelled as such. However, the food industry assures that it does not use nanoparticle-based ingredients in its sweets, cakes and other treats...

Producing "nanofree", is that reasonable?

On 7 June 2017, the NanoRESP Forum addressed the issue of "nanofree" demand, i.e. products that intentionally do not contain or are intentionally deprived of manufactured nanomaterials. Against a backdrop of uncertainty about the dangers of certain nanoparticles (see box), this subject has become topical with the initiatives of the Friends of

Nanobots for water purification

Scientists have revealed spherical microrobots capable of propagating in water and killing bacteria in the water. A scientific innovation that could provide an effective means of treating contaminated water. By swimming through water infected with E. coli, the new robots were able to

Nanotechnologies: What are the drawbacks?

Nanotechnology and nanomaterials use tiny particles of the nanometre (millionth of a millimetre) size and have immense potential to improve our quality of life. However, as with any new technology or development, there are potential drawbacks. A report by GreenFacts (1). One

Nanomaterials in the automotive industry: what advantages, what uncertainties, what promises?

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,

Nanotechnology in our everyday products

As early as the early 2000s, the development of functions and applications using nanotechnology in our daily lives was foreseen. Digital, mobility, housing, health and well-being, energy, environment, leisure and culture, safety, food, etc. All sectors are concerned. Today, innovation is "driven" by uses. The challenge is therefore

Nanotechnology to fight against counterfeiters

Forty million "fake" watches are produced each year in the world, compared to 30 million "real" Swiss watches, according to figures from the Federation of the Swiss Watch Industry. It was in observing this alarming observation that the Swiss startup Nanoga came up with the idea of making "fake" watches more affordable.

Nanomaterials, beware danger!

Nanomaterials are revolutionising everyday products for the benefit of society, but many questions remain unanswered as to the risks that some of them may pose to our health and the environment (1). They are everywhere, including in household waste that ends up in landfills.
