The article provides a comparative analysis of the properties of refractive index-based detection schemes which include localized surface plasmon resonance (LSPR) sensor and surface-enhanced Raman spectroscopy (SERS). LPSR excitation in nanoparticles creates strong extinction and scattering spectra for sensing and spectroscopic applications. SERS has been identified as a sensitive technique observed for molecules found close to silver or gold nanoparticles.
