Morphological and structural characterization of CNDs-R and CNDs-S. a Tapping mode AFM (4.4 × 4.4 μm) from a drop-cast CNDs-R aqueous solution on a mica substrate (scale bar, 1 μm), inset is the height profile along the dashed line; b three-dimensional close-up AFM image (0.5 × 0.5 μm) of CNDs-R; c size histogram with curve fit using a Gaussian model; d FT-IR spectrum of CNDs-S; e XPS survey spectrum of CNDs-S showing the C1s, N1s, and O1s (deconvoluted spectra are in Supplementary Figure 4, *from Au substrate Au4d3, Au4d5, and Au4p)
