Crossing the blood–brain–barrier with transferrin conjugated carbon dots: A zebrafish model study

[Display omitted] •Human transferrin was covalently conjugated to C-Dots.•Transferrin-C-Dots could enter the CNS by crossing the BBB while C-Dots could not.•Zebrafish was used as an in vivo model for the BBB crossing study. Drug delivery to the central nervous system (CNS) in biological systems rema...
