+886-2-8772-8910

The surface-enhanced Raman spectroscopy (SERS) substrate enhances the Raman scattering light from molecules, making high-sensitive Raman spectroscopic analysis possible. A chip of metallic nano/sub-micro structure is mounted on Hamamatsu’s original handling plate to protect its active area. The active area of the handling plate is of a well structure for easily attaching solution or the like. It is noted this is a disposable product and cannot be reused.

 

表面增強拉曼光譜(SERS)基板增強了分子的拉曼散射光,使得高靈敏度的拉曼光譜分析成為可能。將金屬納米/亞微結構芯片安裝在Hamamatsu原創的載板上,以保護其有效面積。 它是一次性產品,不能重複使用。

SERS
SERS is a method for enhancing Raman scattering light (Raman scattering light is typically weak.). The scattering light generated on incidence to molecules is mainly scattering light (Rayleigh scattering light) of a wavelength common to that of the incident light. In addition to the Rayleigh scattering light, a faint amount of the scattering light (Raman scattering light) of wavelengths different from that of the incident light is emitted. The difference (Raman shift) in the frequencies between the incident light and the Raman scattering light comes from the natural frequencies of the molecules. Spectrometry of the Raman scattering light reveals information about a type and a structure of the molecule (type of chemical bond, level of crystallization, distortion of crystal lattice, etc.). For example, glucose and galactose are isomers that have nearly the same chemical structures, but they can be distinguished by Raman spectroscopic analysis.
The enhancement of the faint Raman scattering light by the SERS substrate facilitates spectrometry. When a minute metal (Au) structure formed by nanoimprint technology is exposed to light, and interaction (surface plasmon resonance) occurs between the light and the electrons of the metal surface, creating an enhanced electric fi eld. This effect enhances the Raman scattering light of the molecules that are close or attached to the metal surface.
