Characterization of NP aerosol deposition onto polyester (PET) hanging inserts in in vitro cell-free experiments. The dose delivered (expressed in µg/cm2) was extrapolated using a Matlab code as describes in Section 2. The deposition efficiency was calculated by diving the delivered dose by the nominal concentration of the NP suspension (expressed in µg/cm2). Here we reported the data obtained analyzing with Matlab the representative images reported in Figure 1 and Figure 2. The experiment was performed twice with comparable results.
