SURFACE-ENHANCED RAMAN SENSOR

The production, morphology, and optical properties of HNO3 etched silv er foil, used as an effective sensor for surface-enhanced Raman scatte ring (SERS) analysis, are reported. These foils were found to exhibit a strong SERS effect and excellent stability, reversibility and spectr al response. Acridine, 9-aminoacridine and quinacrine have been taken to illustrate the usefulness of this sensor. Simplicity, low cost, spe ed and availability are outstanding features of this sensor, which ext ends the applicability of the SERS technique to more practical situati ons.
