Figure 6

Linescans and corresponding reflectance (top) and fluorescence (bottom) images of half Ag/half Au nanowires coated with 5′ thiol, 3′ TAMRA probe oligonucleotides of different lengths. The 24-base probe did not have secondary structure; however the 34- and 48-base probes were molecular beacons with self-complementarity at the 5′ and 3′ ends. Unlabeled complementary DNA was present in all cases to extend the probes from the surface. The black trace (reflectance) corresponds to the axis on the left, and the red trace (fluorescence), to the axis on the right.
