Nanoparticles are found in many everyday products, from cosmetics and textiles to air pollution. While they offer many benefits, scientists still need better ways to understand how long-term exposure may affect our skin. Researchers from Alfaro-Moreno group at INL have developed a new skin-on-a-chip platform that closely mimics human skin, providing a more realistic way to study how nanoparticles interact with our body's first protective barrier. Unlike conventional lab models (which grow...
