Characterization of DAO/DEX-CNGs. A TEM, B, C cryo-EM, D SEM, E–G fluorescence images, and H optical bright-field of DAO/DEX-CNGs. The inset to A: HRTEM images of corresponding DAO/DEX-CNGs. Inset in H: size distribution histograms of corresponding DAO/DEX-CNGs. Fluorescence images of DAO/DEX-CNGs were recorded at excitation wavelengths of E UV (330–385 nm), F blue (450–480 nm), and G green (510–550 nm). The scale bars in E to H represent 10 μm
