An ectopic surface-enhanced Raman scattering substrate structure and its near-field detection method

The present invention discloses a substrate structure for surface-enhanced Raman scattering at an off-site and its near-field detection method. The Raman scattering substrate structure includes a substrate and two-dimensional nanosheets assembled on the substrate by a self-assembly method. The two-dimensional nanosheets are polygon structures made of a metal material with surface plasmon characteristics and having at least a pair of parallel end faces. The thickness of the two-dimensional nanosheets is in the nanometer scale, while the side length is in the micrometer scale. When one end face of the two-dimensional nanosheet is excited by an excitation light source, a surface plasmon signal that travels along the surface of the nanosheet is formed and finally output at the other end face parallel to it. The emitted signal interacts with the analyte molecules, and Raman signals are formed at positions different from the excitation light source, thereby preventing the analyte molecules from decomposing due to the irradiation of a high-density light intensity excitation light source. At the same time, the off-site acquisition of Raman signals also avoids the interference of the excitation light source.
