Fabricating nano-PCB mimics with DCIMP. a A seven-segment digit 8 design is employed to fabricate nano-PCB mimics on a rectangular origami. To show the generality, we fabricated digits from 0 to 9 and several typical alphabets, as shown in corresponding AFM images. b Schematic illustration of the fabrication process of Cu-Ag bi-metallic nanocircuits. c AFM characterization of the Cu-Ag bi-metallic sample prepared at different stages. The size of the integrated panel is 100 × 280 nm2. Scale bars: 50 nm.
