SERS-based immunoassay on 2D-arrays of Au@Ag core-shell nanoparticles: influence of the sizes of the SERS probe and sandwich immunocomplex on the sensitivity
© The Royal Society of Chemistry. We report a sandwich-type SERS-based immunoassay using a two-dimensional (2D) array of gold core@silver shell (Au@Ag) nanoparticles (NPs) as the SERS substrate and antibody-conjugated gold NPs labeled with 4-mercaptobenzoic acid (MBA) as the SERS probes. To achieve...
