Multilayered shell SERS nanotags with a highly uniform single-particle Raman readout for ultrasensitive immunoassays?

Chemical Communications Pub Date: 2012-08-02 DOI: 10.1039/C2CC34115H

Abstract

Novel SERS nanotags with highly uniform and reproducible signals have been developed by the layer-by-layer assembly and crosslinkage of small silver nanoparticles at the surface of silica particles, which opens an avenue to the quantitative and reliable SERS application in bioassays.
