Nanos and Health
Nanos and health
In many areas (or a previous cosmetic accident repair?, diet, textile, BTP, medicine, ...), 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 sought can lead to adverse health effects, for which many uncertainties remain... and concerns: due to their increased reactivity, nanomaterials are in fact likely to cause toxicity and harmful effects. potentially stronger than “conventional” materials of the same chemical nature.
The studies carried out so far are mainly vitro, and the studies in vivo are mainly in animals, with toxic effects demonstrated in the heart, liver, spleen, stomach and kidneys in particular.
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 article published in 2021, the nanoparticles presenting the greatest risk to human health would be the nano-TiO2 (titanium dioxide), silver nanoparticles, silicon dioxide (silica) and carbon nanotubes.
