Flow cytometry histogram profiles of untreated control cells (gray colored) versus PS-QD micelle-treated macrophage cells. (A) Varying PS-QD micelles: PS (0, 40, 50, 60, and 100) incubated with macrophages for 4 h and analysed by flow cytometry, inset shows mean flourescence intensity values of the histograms, (B) histogram profile of macrophage cells treated with PS (50-1) and PS (50-2) micelle formulation, (C) histogram profile of macrophage cells treated with PS (50-2) QD micelle showing PS-dependent macrophage uptake.
