The goal of this work was to refine an ALI pre-established protocol for the VITROCELL® Cloud 6 system. Therefore, after addressing each crucial step, (i.e., the use of very low concentrations of NP, the deposition of a homogeneous layer of surfactant, the specific use of semi-adherent cells, and finally the enhancement of the extraction yield of RNA to carry out transcriptomic studies), we present here for the first time a robust almost ready-to-use protocol. This one will be helpful for nanotoxicologists interested in developing such methodologies.
