Cell uptake of siRNA nanoparticles fabricated by Au-G3 vs. G3 PPI dendrimers at different N/P ratios by flow cytometry. (a). Percentage of cell uptake as a function of N/P ratio. (b). Mean green fluorescence intensity of each individual cell as a function of N/P ratio. A549 cells were incubated by Au-G3/siRNA and G3/siRNA respectively at 37 °C for 24 h at N/P ratios of 0.6, 1.2, and 2.4. The percentage of cell uptake and the mean green fluorescence intensity of each individual cell were calculated based on data collected from a population of 10000 gated cells.
