Plasmonic sensing has been an important multidisciplinary research field and has been extensively used in detection of trace molecules in chemistry and biology. The sensing techniques are typically based on surface-enhanced spectroscopies and surface plasmon resonances (SPRs). This review article deals with some recent advances in surface-enhanced Raman scattering (SERS) sensors and SPR sensors...

Visible light-activated localized surface plasmon resonance-based photoelectrochemical detection is reported for the first time.

We demonstrate theoretically that plane wave propagating in free space can be used to excite the whispering gallery mode in dielectric microresonators grown on the top of nanoplasmonic structures, with the assistance of surface plasmon wave. We have demonstrated the coupling modes using both localized and propagating surface plasmon-supporting nanostructure surfaces.

Localized surface plasmon resonance (LSPR) is strongly associated with inelastic scattering of biochemical molecules near metal nanostructures, i.e., surface enhanced Raman scattering (SERS). Systematically exploration of the relationship between surface-enhanced Raman spectroscopy (SERS) and the plasmon resonance wavelength has been an experimental limitation due to the lack of reliable and tu...
