Fig. 1From: Quantification of the cellular dose and characterization of nanoparticle transport during in vitro testingMethod used to determine the effective dose reaching the cell monolayer 1) incubation of the NPs in wells with and without cells. 2) At each time point, transfer of the supernatant into an empty well for UV-vis measurements 3). The cellular dose is then determined by subtracting the calculated areas under the absorbance curves at t = 0 s to the one of the considered time pointBack to article page
