Nanoparticles and pregnancy: Placental impairment disrupts the formation of blood vessels

By Lisa McDonald / June 14, 2024

There is ample evidence that nanoparticles can affect the healthy growth of a fetus, but the mechanisms involved are largely unknown. An interdisciplinary team led by Empa researchers showed that nanoparticles can cause indirect harm by disrupting the production of messenger substances in the placenta, leading to impaired blood vessel formation.
