Abstract
A surface enhanced Raman spectroscopy (SERS) apparatus, system and method employ a plurality of nanorods configured to vibrate. The apparatus includes the nanorods having tips at free ends opposite an end attached to a substrate. The tips are configured to adsorb an analyte and to vibrate at a vibration frequency. The apparatus further includes a vibration source configured to vibrate the free ends of the nanorods at the vibration frequency in a back-and-forth motion. Vibration of the nanorods is configured to facilitate detection of a Raman scattering signal emitted by the analyte adsorbed on the nanorod tips. The system further includes a synchronous detector configured to receive the Raman signal and to be gated cooperatively with the vibration of the nanorods. The method includes inducing a vibration of the nanorods, illuminating the vibrating tips to produce a Raman signal, and detecting the Raman signal using the detector.
