Abstract

The invention provides a surface-enhanced Raman scattering substrate and a trace detection method of a biological and chemical analyte using the same. The substrate includes: a substrate having a periodic nanostructure; a reflection layer formed on the substrate; a dielectric layer formed on the reflection layer; and a metal thin film layer formed on the dielectric layer.
