ALI systems are considered to be a promising exposure system to study toxicological e ects of airborne nanomaterials instead of in vivo inhalation studies and have been widely used to assess the toxicology of nanomaterials in recent years. However, the robustness of these methods is not yet wellunderstood. Here we reported a C&E analysis of a commonly used flow through ALI exposure system.
