Simutaneously intensified plasmonic and charge transfer effects in SERS sensors using MXene-coated Au NPs assembly |
| 초록 |
SERS is an ultrasensitive tool for detecting a wide range of analytes. The signal amplification mechanisms are localized surface plasmonis resonance (LSPR) and charge transfer (CT) effect between the analyte and the surface of substrate. Conventional researchs have limitation in simutaneously work both mechanisms. Herein this study presents the ultrasensitive SERS platform utilizing Au NPs coated with MXene layer to align Fermi level for simultaneously work both mechanisms. In addtion, wrinkled structure which occured by MXene layer would help increase the EM effect by guiding the analyte to be captured near the hot spot center. The SERS platform exhibits a large enhancement factor up to 1.6x1010. Ferthermore the limit of detection of Cr(VI) is 13 ng/L. This SERS platform can be generalized for quantitative detection wide range of analyte. |
