Fig. 4. (A) Representative, low-magnification SEM image (10 × 10 μm2) of gold nanorods organised in single lines on a wrinkle-substrate. (B) Gold nanorods organised in single lines show a remarkably low amount of morphological impurities. The magnified inset highlights the high degree of order as well as the small interparticle gap sizes. (C) Corresponding AFM image (10 × 10 μm2) with cross-sections measured (D) perpendicular to the wrinkles (in green) and (E) along the channel direction (in red).
