Substrate and apparatus for surface enhanced Raman spectroscopy |
摘要 |
A substrate and apparatus for qualitatively and quantitatively detecting constituents of an environment by surface enhanced Raman spectroscopy. The substrate is composed of two separate phases: an adsorbing phase which has an affinity for the molecular constituents of interest, and a metallic phase that possesses the specific geometry, chemical and electromagnetic properties required to enhance emission of Raman signal frequencies of adsorbed molecules. An apparatus is provided which includes a monochromatic light source, a means to transmit the desired wavelength from the light source to the surface substrate surface, a means to collect the scattered Raman signal frequencies and transmit them to a detector, and a means to analyze the recorded response.
