We describe a general framework to design nanobiosensors based on a wired enzyme coupled to a redox molecule and integrated with SERS Au core-shell nanoparticles and ordered nanocavities. The response of the proposed sensor is based on the different electronic resonant Raman behavior of the oxidized or reduced electronic states of the molecular wire, and on the surface plasmon amplification induced by the tailored metallic substrate. The nanobiosensors can be interrogated remotely through the…

Turning on resonant SERRS using the chromophore-plasmon coupling created by host-guest complexation at a plasmonic nanoarray.
An active molecular plasmonics system is demonstrated where a supramolecular chromophore generated in a host-guest binding event couples with the localized surface plAsmon resonance (LSPR) arising from gold nanodisc gratings to validate the role of resonance in turning on the spectrum.
