Abstract
A nanoagent includes at least one nanocomposite. The nanocomposite includes at least one gold nanorod, a silver layer coated on an outer surface of the gold nanorod, a Raman reporter molecule layer coated on the silver layer, a pegylated layer coated on the Raman reporter molecule layer, an active layer conjugated to the pegylated layer. the active layer includes at least one of a targeting molecule configured to bind to a target of interest, and a functional molecule configured to interact with the target of interest. The silver layer has silver nanoparticles. The Raman reporter molecule layer has Raman reporter molecules that are detectable by surface enhanced Raman spectroscopy (SERS). The pegylated layer has at least one of thiolated polyethylene glycol (HS-PEG), thiolated polyethylene glycol acid (HS-PEG-COOH) and HS-PEG-NHx.
