Figure 4.
(A) Laser confocal assay was used to evaluate the uptake of Bodipy-labeled NP and AMD-NP by Caov3 cells and CHO cells in vitro. Blue represents the nucleus (DAPI) and red represents the fluorescent (Bodipy) labeled NPs. Scale bar=25 μm. (B) Competitive cell uptake study was performed by pre-addition of free AMD3100 with different concentrations using flow cytometry. (C) Quantitative analysis of flow cytometry. Data are presented as the mean±SD (n=3). **p<0.01.
