Raman Dye-Labeled Nanoparticle Probes for Proteins

Abstract

In this paper, we demonstrate how one can chemically design Raman dye-functionalized nanoparticle probes with specific protein-binding affinities and use these probes, coupled with surface-enhanced Raman scattering (SERS) spectroscopy, to perform multiplexed screening of protein-small molecule interactions and protein-protein interactions in a protein microarray format.
