The plasmonic enhancement of fluorescence and scattering is built up by the local field created in nanostructures of silver and gold sustaining localized surface plasmon resonances (LSPR). The plasmon properties in metallic nanostructures depend on their shapes, sizes and the dielectric properties of the metal and the environment. Therefore, the fabrication of nanostructures with controlled plasmon properties is at the heart of practical applications. One of the main objectives of the research work presented in this thesis was to develop reproducible protocols for coating the silver colloids to form shell-isolated nanoparticles, and extend the work to different shapes. The fabricated nanostructures are explored in plasmon enhanced fluorescence (SHINEF) and plasmon enhanced Raman scattering (SHINERS) of molecules in solution and on Langmuir-Blodgett monolayers.
