Vibrating tip surface enhanced Raman spectroscopy |
摘要 |
A vibrating tip surface enhanced Raman spectroscopy (SERS) apparatus, system and method employ a nano-needle configured to vibrate. The apparatus includes the nano-needle with a substantially sharp tip at a free end opposite an end attached to a substrate. The tip is configured to adsorb an analyte. The apparatus further includes a vibration source configured to provide an alternating current (AC) electric field that induces a vibration of the free end and the tip of the nano-needle. Vibration of the nano-needle under the influence of the AC electric field facilitates detection of a Raman scattering signal from the analyte adsorbed on the nano-needle tip. The system further includes a synchronous detector configured to be gated cooperatively with the vibration of the nano-needle. The method includes inducing the vibration, illuminating the vibrating tip to produce a Raman signal, and detecting the Raman signal using the detector.
