Once in the lung microcirculation, the RBC-bound NPs are mechanically detached from the RBCs when the RBCs are squeezed through the tiny capillaries of the air–blood barrier and transferred to the endothelium by nonspecific interactions. When decorated with vascular endothelium-specific ligands

In contrast, particle uptake following dermal exposure has so far not been observed as nanoparticles do not penetrate beyond the most superficial skin

• Abstract The air–blood barrier is a very thin membrane of about 2.2 µm thickness and therefore represents an ideal portal of entry for nanoparticles to be used therapeutically in a regenerative medicine strategy. Until now, numerous studies using cellular airway models have been conducted in vitro in order

• to investigate the potential hazard of NPs. However, in most in vitro studies a crucial alveolar component has been neglected. Before aspirated NPs encounter the cellular air–blood barrier, they impinge on the alveolar surfactant layer (10–20 nm in thickness) that lines the entire alveolar surface

• . Thus, a prior interaction of NPs with pulmonary surfactant components will occur. In the present study we explored the impact of pulmonary surfactant on the cytotoxic potential of amorphous silica nanoparticles (aSNPs) using in vitro mono- and complex coculture models of the air–blood barrier
