SERS enhancement of silver nanoparticles prepared by a template-directed triazole ligand strategy

Chem Commun (Camb). 2015 Aug 21;51(65):13028-31. doi: 10.1039/c5cc02883c.

Abstract

Two advances in the development of a one-pot method to prepare silver nanoparticles (AgNPs) using the Tollens' reagent are described. First, a template-directed process of AgNP synthesis using resorcinol triazole ligands bearing two pendent galactose sugars is shown. Second, the conversion of these AgNPs into SERS nanotags is demonstrated using malachite green isothiocyanate as the Raman reporter molecule.
