In the quest for understanding and applying nanoscale processes, molecular detection has attained great interest due to its effectiveness in medicine, biology and pharmacology. Raman spectroscopy is one of the most reliable techniques for the identification and characterization of molecules, which has a limited capacity to detect molecules in diluted samples because of low signal yield. Surface-enhanced Raman spectroscopy (SERS) uses large electromagnetic fields produced locally by metal nanostructures to improve the Raman scattering and boost sensitivity of molecules at lower level concentrations, for example the Raman signal of standard dyes such as R6G can be enhanced by more than one billion-fold.References
