Characterization of the ND-R conjugates formed by the process outlined in Figure 2. (A) A graph of the size distribution of ND (solid line) compared with ND-R conjugates (dashed line) obtained using DLS. The increase in size of ND-R indicates the loading of DNR onto the ND surface. The inset images are taken using TEM, to visualize the differences in the surfaces of ND (top) and ND-R conjugates (bottom). The clear boundaries between ND particles are visible in the top image. The bottom image shows the textured surface present on the ND-R conjugates. This organic layer is indicative of the binding of DNR. (B) FTIR spectra of ND (gray line), DNR (red line), and ND-R (purple line). The spectra confirms the loading of DNR onto ND platforms because the ND-R spectra contains peaks that are characteristic of both ND and DNR spectras.
