Fig. 3. (A) Native gel electrophoresis characterization of C-HCR and its individual upstream HCR-1 and downstream HCR-2 systems. The “+” and “–” denote the presence and absence of the corresponding DNA components, respectively. (B) AFM image and cross-section analysis of the resulting C-HCR-motivated dsDNA branched nanowires. (C) AFM characterization of the C-HCR system without initiator. (D) AFM image of HCR-1-motivated linear dsDNA nanowires. For detailed experimental conditions see Experimental section.
