Bioelectronics: Induced SER-Activity in Nanostructured Ag–Silica–Au Supports via Long-Range Plasmon Coupling (Adv. Funct. Mater. 12/2010)

The picture shows a nanostructured layered silver-silica-gold electrode developed by J.-J. Feng, I. M. Weidinger, et al. on page 1954 where the underlying silver surface can be excited by laser light. The resulting surface plasmon resonance is transferred over a distance of up to 20 nm to the outer gold layer where attached proteins can be detected by surfaceenhanced Raman spectroscopy.
