Enhancement of sers signal using of new
material based on cerium dioxide facet dielectric films
Abstract
In this paperweinvestigatedthe possibilityof the facetstructures, based on cerium dioxidefor the purpose ofincreasing the intensity ofthe SERS
signal. During the studies a newmetamaterialwas developed. The metamaterial is based on the facet cerium
dioxide filmsand plasmonicnanoparticles that are immobilizedon its
surface. The new metamaterialprovides additional
SERS signal amplificationfactor more
than 200. Thus developed materialoffers the prospectof increasing the sensitivity and selectivityof biochemicalandimmunologicalanalysis.
Key words: Surface Enhancement Raman
Scattering, cerium dioxide, metamaterials, facet structure, biosensors,
immunoassay.
