Abstract
Gold nanoparticles functionalized with 4-mercaptobenzoic acid can selectively capture Hg2+ in the presence of 2,6-pyridinedicarboxylic acid, generating a fingerprint surface-enhanced Raman scattering (SERS) peak at 374 cm−1. This SERS sensor exhibits a limit of detection of 5 ppt toward Hg2+ in water.
