NP uptake in human PBMCs and mouse Hepa 1–6 cell line. Percent of Hepa 1–6 (a and c) and monocytes (b and d) which uptake PLGA-Rhod NPs (a and b) and PLGA-Rhod/PEI NPs (c and d) at different time points. Mean fluorescence intensity (MFI) of Hepa 1–6 (e and g) and monocytes (f and h) loaded with different concentration of PLGA-Rhod NPs (e and f) and PLGA-Rhod/PEI NPs (g and h), at different time points
