Typical two-color merged confocal fluorescence microscopy images of live HeLa cells exposed to NPs (green); times after the start of NP incubation is given in the panels. (a–c) DPA-QDs, 10 nM in PBS; (d–f) DHLA-AuNCs, 20 µg/mL in serum-free DMEM. Scale bar, 10 µm. Cell membranes (stained with CellMask DeepRed) are depicted in red.
