| 摘要 |
An analyte stage for use in a spectroscopy system includes a tunable resonant cavity that is capable of resonating electromagnetic radiation having wavelengths less than about 10,000 nanometers, a substrate at least partially disposed within the cavity, and a Raman signal-enhancing structure at least partially disposed within the tunable resonant cavity. A spectroscopy system includes such an analyte stage, a radiation source, and a radiation detector. Methods for performing Raman spectroscopy include using such analyte stages and systems to tune a resonant cavity to resonate Raman scattered radiation that is scattered by an analyte.
