Fig. 3From: Immune cell targeting nanoparticles: a reviewA Synthetic scheme of the drug loaded CDs/Man-NPs nanocomposite. B Cell uptakes of activated macrophages, untreated macrophages and 4 T1 cell were assessed by confocal laser scanning microscopy. Each cells were treated with CDs/Man-NP and unmodified CDs/NPs, respectively. The differential interference contrast microscopy of cells, NPs (blue) and overlays of the two images. Scale bar = 20 μm.
