Between February and April 2023, at least three food products and five sunscreen products containing titanium dioxide were recalled on the Recall Conso website:
- In line with previous controls, three food products were recalled because they contained the additive E171, banned in France since 2020:

- The sunscreen products recalled contained nanoparticles of titanium dioxide at a concentration higher than the maximum authorized level (25%):

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.
