Fabrication of Highly Rough Ag Nanobud Substrates and Surface-Enhanced Raman Scattering of -DNA Molecules
Figure 2
SEM and EDS analyses of AgNB structures. (a) SEM image of AgNB structures (the external electric current is 12 μA in the fabrication process). AgNB structures were highly rough, dense, and unidirectional, composed of tightly collocated 100 nm sized units like nanoscale buds growing in the same direction. (b) SEM image of AgNW structures with disordered and loose configuration obtained by decreasing the external electric current to 3 μA in the fabrication process. (c) EDS analysis of AgNB structures.
