Energy dispersive X-ray spectroscopy (EDS) characterization of DNA- (left panels) and eDNA-coated (right panels) lattices. (a) SEM image of a DNA-coated lattice and its phosphorus elemental map that shows inhomogeneous distribution. (b) A zoomed-in SEM image of a horizontal beam, its phosphorus elemental map, and EDS spectrum (bottom). Outlined rectangles in red represent grooves on the beam, rectangles in orange correspond to the ridges on the beam, and rectangles in green mark nodes that contain a vertical beam. (c) SEM image of an eDNA-coated lattice and its elemental map that shows homogeneously distributed phosphorus. (d) A zoomed-in SEM image of a horizontal beam, as well as its EDS spectrum, that shows phosphorus present in the grooves, along the ridges, and on the node.
