Confocal microscopy images of 72 hpf zebrafish embryos (a) incubated with 500 µg/mL of C-NEs labeled with DiR and TopFluor-PC, for 4 h at 34 °C. Control refers to non-treated zebrafish, which present auto-fluorescence. Scale bars correspond to 250 µm. (b) Z-stack images. Red channel: DiR. Green channel: TopFluor-PC.
