Fig. 2From: Nanoparticles engineered to bind cellular motors for efficient deliveryCellular distribution of NPs. a, d Mean fluorescence intensity (MFI) of intracellular Au@tiopronin modified with DynPro (Au@DynPro) or IntCt (Au@IntCt) after 1 h incubation with Vero cells (a) and other cell lines (d). Differences in MFI between Au@DBPs and Au@IntCt (control) were statistically significant p value of 0.001 (α = 0.05). In contrast, differences among Au@DBPs were not significant with a p value of 0.3 (α = 0.05; not shown). b Representative confocal images of Vero cells incubated with Au@DynPro or c Au@IntCt. e–h Representative confocal images of SK-N-MC (e), HeLa (f), 293T (g) and MDCK cells incubated with Au@DynPro. Scale bar: 10 µm. i Time-dependent accumulation of Au@DynPro at several time points between 20 and 120 min, as indicated. j Fluorescence intensity percentages at increasing doses of Au@DynPro quantified by flow cytometryBack to article page
