18/01/2022
The European regulation 2022/63 of January 14, 2022 banning the food additive titanium dioxide (E171) has been published in the Official Journal of the EU. It will come into effect on February 8, 2022 and extends to the other EU countries. The suspension measure has been in force in France since January 1, 2020.
From August 8, 2021, food containing E171 can no longer be placed on the market. Those that had been previously allowed, will be able to remain so until their date of minimum durability or their use-by date. As of 2025, this colorant could also be banned in medicinal products.

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.
