As an advanced analytical tool, surface-enhanced Raman scattering (SERS) has broad
applications in identification of colorants in paints and glazes, hazard detection to ensure
food safety, biomedicine and diagnosis, environmental monitoring, detection of explosives
and forensic science. In this review, main types of plasmonic substrates, which include solid
substrate with metallic nanostructures and chemically synthesized noble metal colloids, and
their fabrication methods are reviewed. The design principles for fabrication of ultrasensitive …

Due to their favorable optical properties, nanostructures supporting surface plasmons have
attracted considerable attention for a broad range of applications. Surface enhanced Raman
scattering is one of the most important applications of plasmonic structures. In this thesis, the
optical properties of plasmonic structures based on periodic nanoparticle arrays are
investigated. New SERS substrates are developed that take advantage of the properties of
these structures. It is demonstrated that the substrates can provide average SERS …
