Parameters for selective colorimetric sensing of mercury(II) in aqueous solutions using mercaptopropionic acid-modified gold nanoparticles

Chem Commun (Camb). 2007 Mar 28:(12):1215-7. doi: 10.1039/b615383f. Epub 2006 Dec 11.

Abstract

We unveil a new homogeneous assay-using mercaptopropionic acid-modified Au nanoparticles in the presence of 2,6-pyridinedicarboxylic acid for the highly selective and sensitive detection of Hg(2+) ions.
