| 摘要 |
Surface-enhanced Raman spectroscopy (SERS) uses nanoscale metal particles (SERS-active particles) or surface roughness to enhance the Raman signal of Raman-active analytes contacting the surface. SERS sandwich particles contain SERS-active particles (12, 14) sandwiching a Raman-active substance (16) and serve as optical tags. |
