Self-Exciting Surface Enhanced Raman Spectroscopy

摘要

Self-exciting surface enhanced Raman spectroscopy (SERS) employs an integral optical excitation source to provide an excitation signal to provide self-excitation of a SERS structure. The SERS structure includes a plurality of nanofingers having SERS-enhancing nanoparticles disposed adjacent to the nanofingers.
