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 properties for which they are researched can lead to undesirable effects on health, for which there are still many uncertainties… and concerns: 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, and 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 generalizable to humans but still provide valuable information on the potential for adverse health effects.
According to a scientific paper published in 2021, the nanoparticles with the greatest risk to human health would be nano-TiO2 (titanium dioxide), silver nanoparticles, silicon dioxide (silica) and carbon nanotubes.
