Fig. 4. Dark-field optical images of nanodisk arrays. A, B, and C correspond to Fig. 1 D, E, and F, respectively. (Scale bars, 10 mm.)

Fig. 5. Raman spectrum of methylene blue on Au nano disk arrays. The intense C–C ring stretch mode of MB at 1,621 cm^–1 was monitored to draw these Raman images in Fig. 2.

Fig. 6. Zoomed-in SEM images from Fig. 1C. Shown are zoomed-in from the upper-right first (A) and second (B) regions in Fig. 1C. Green arrows point to Ni disks sandwiched by Au nanodisks. (Scale bars, 100 nm.)
