Abstract
A method of identifying a sample includes placing the sample in proximity to a plurality of nanoparticles and irradiating the plurality of nanoparticles with laser radiation. A plasmon resonance process results in heating of the plurality of nanoparticles due to the laser irradiation. The method also includes transferring energy from the plurality of nanoparticles to the sample, obtaining a Raman spectrum associated with sample, and identifying the sample based on the Raman spectrum.
