Fig. 5From: Research on the fate of polymeric nanoparticles in the process of the intestinal absorption based on model nanoparticles with various characteristics: size, surface charge and pro-hydrophobicsStudy on the endocytosis of model NPs: Relative uptake of PSNPs (a), CMCNPs, CHNPs (b), PNPs and PPNPs (c) by caco-2 cells after adding endocytosis inhibitor(data are mean ± SD, n = 3, *p < 0.05,**p < 0.01, ***p < 0.001; Compared with the control group without any inhibitor, #p < 0.05, ##p < 0.01). The relative permeability of PSNPs (d), CMCNPs, CHNPs (e), PNPs and PPNPs (f) in the eversion intestinal sac model after adding endocytosis inhibitor (data are mean ± SD, n = 3, *p < 0.05,**p < 0.01, ***p < 0.001; Compared with the control group without any inhibitor, #p < 0.05, ##p < 0.01)Back to article page
