摘要: Surface-enhanced Raman scattering(SERS) is a molecular specific spectroscopic technique that amplifies the Raman signal of absorbed molecules for up to 1010times. Over the past decades, SERS substrates experienced rapid growth, resulting in excellent development for SERS analysis. Because the surface plasmonic resonance coupling between individual materials can form a "hotspot" region to maximize the Raman signal, among many substrate construction strategies, self-assembly attracts more attention in constructing superstructures with strong, uniform and stable SERS activity. In addition, a number of plasmon-free nanomaterials with appropriate superstructures samely show enhanced SERS activity, which is primarily attributed to the formation of the optical resonator. This review aims to provide a scientific synopsis on the progress of self-assembled superstructures for SERS and ignite new dis˗ coveries in the SERS platform, as well as SERS applications in various fields.
