Abstract

A tunable apparatus for performing Surface Enhanced Raman Spectroscopy (SERS) includes a deformable layer and a plurality of SERS-active nanoparticles disposed at one or more locations on the deformable layer, wherein the one or more locations are configured to be illuminated with light of a pump wavelength to cause Raman excitation light to interact with the nanoparticles and produce enhanced Raman scattered light from molecules located in close proximity to the nanoparticles. In addition, a morphology of the deformable layer is configured to be controllably varied to modify an intensity of the Raman scattered light produced from the molecules.
