Analysis of uptake and transport of particles through the intestinal epithelial Caco-2 cell monolayer after 24 h incubation in a Transwell® system. A Representative fluorescence microscopic images. Gray spots indicate the Caco-2 cells and colored spots indicate particles. B Representative confocal microscopic images. Green spots indicated the Caco-2 Monolayer and red spots the particles. C Fraction of particles interacting with the Caco-2 cell monolayer (uptake or laying on top of the cells) determined with a plate reader. D Percentage of particles transported through the Caco-2 cell monolayer determined with a plate reader. Data are shown as mean values ± standard deviation of three independent experiments
