SERS
Surface Enhanced Raman Scattering (SERS) is a powerful technique that enables molecular fingerprint-based ultra-sensitive detection through an enhanced electromagnetic field generated by plasmonic nanoparticles. This technique has found extensive use in photochemical reactions due to its ability to enhance reaction rates and decrease energy barriers at the nanoscale.
In this study, we demonstrated SERS detection of a chemical reaction induced by optical heat generated inthe vicinity of plasmonic nanoparticles and substrates. The generated heat facilitates an interaction between the amine group (-NH2) on the smooth Ag substrate and the carboxylic acid (-COOH) on the Au nanoparticle. This interaction leads to the formation of an amide bond through dehydration, which is confirmed by the new appearance of specific vibrational peaks in the SERS spectrum.
