Nanocomposites, methods of making same, and applications of same for multicolor surface enhanced raman spectroscopy (sers) detections

Abstract

A method of making at least one nanocomposite for surface enhanced Raman spectroscopy (SERS) detection of a target of interest includes forming at least one gold nanorod; coating a silver layer on an outer surface of the gold nanorod; assembling a Raman reporter molecule layer on the coated silver layer, wherein the Raman reporter molecule layer comprises Raman reporter molecules that are detectable by the SERS; coating a thiolated polyethylene glycol (PEG) layer on the assembled Raman reporter molecule layer; and conjugating the coated thiolated PEG layer with molecules of an antibody to make the at least one nanocomposite.
