Quasi-periodical 3D hierarchical silver nanosheets with sub-10 nm nanogap applied as an effective and applicable SERS substrate

Journal Article


Abstract


  • Surface-enhanced Raman scattering (SERS) is considered

    as the most promising trace detection method since its first

    discovery on rough silver electrodes in 1974.[1] After years of

    development, it has exhibited great potential as a nondamaging

    single molecule analysis method applied in a wide range

    of areas, including biological labeling,[2] chemistry,[3] agriculture,[

    4] environmental science,[5] food safety,[6] and so forth.[7]

    The origin of the SERS effect is still in dispute but there is an

    agreement on an electromagnetic enhancement mechanism

    (EM)[8] due to the excitation of the localized surface plasmon

    resonance (LSPR) on the nanostructures with existance of

    nanogaps.[9] Enhancement efficiency and applicability are the

    two factors that evaluate the SERS substrate. The effeciency

    means the substrate can trace molecules sensitively, reproducibly,

    and precisely, while the applicability indicates the SERS

    substrate can be prepared easily at low cost.
