| 摘要 |
A method of performing surface-enhanced resonant Raman spectroscopy (SERRS) in respect of a sample (100) provided on an aggregated colloid nano-particle having a plasmon absorption band similar to that of a target molecule. The sample is irradiated at a first wavelength (lambda1).coinciding with the absorption band of the plasma, to obtain (12) a SERRS spectra for deriving (10) a fingerprint of the target melecule, and at a second wavelength (lambda2), coinciding with the absorption band caused by aggregate of said nano- particles, to obtain (14) a SERS spectra for monitoring (16) said aggregation.
