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.

Understanding Nanoscience (Paris Saclay University, Online)
On line
Training
  • MOOC from April 28 to June 22, 2025
  • Public who has carried out two or more years of scientific studies at university, as well as professionals or the self-educated who want to discover, learn more or acquire specific knowledge in some area of nanoscience.
  • Organizer: Paris Saclay University
  • Course paln:
    • Theme 1: Introduction to nanoscience and nanotechnology – Let’s lay the foundations and discover the key concepts of this field.
    • Theme 2: How can you “see” and fabricate nano-objects? We will discover what tools are used to observe matter at these scales and what techniques the scientist can use to make objects that are only a few billionths of a meter in size.
    • Theme 3: Nanochemistry – From carbon to porous solids and nanoparticle synthesis; applications of the field.
    • Theme 4: Nanophysics – Quantum effects and nanoelectronic devices; optical nanostructures: the confinement of light and emission; nanosensors; applications of the field.
    • Theme 5: Nanobiology, Nanomedicine, Micro-nanofluidics – The study and manipulation of molecules; treating diseases with nanomedicine; the on-chip manipulation of liquids for medical diagnosis; applications of the field.
    • Theme 6: Nanoscience and Society: Are Nanotechnologies dangerous? Societal, health and environmental issues.
