| Abstract: | In Raman spectroscopy, inelastic scattering of photons from an atomor molecule in chemical entities is utilized to analyze
the composition of solids, liquids and gases. However, the low cross-section limits its applications. The introduction of
surface-enhancedRamanspectroscopy in 1974has attracteda lot of attention fromresearchers due to the large enhancement of weak
Raman signal,which facilitates identification in chemical and biological systems. Recently, single-molecule Raman scattering
has enhanced the detection sensitivity limit of Raman Spectroscopy. |
