a NH-GQDs, b TAT-NGs (1:1), c TAT-NGs (5:1), d TAT-NGs (10:1), and e FAPEG-TNGs. f The endonuclear fluorescence intensity of TAT-NGs and FAPEG-TNGs relative to that of NH-GQDs (the images are overlaid with the blue color of NH-GQDs derivatives and the red color of nuclei stained with 7-aminoactinomycin D (7-AAD, Component B). Scale bars, 20 μm).
