Abstract

A colorimetric system using noble metal nanoparticles (NPs), for the detection of small concentrations of mercury ion (Hg2+) in water is described. Fluorescein-functionalized Au and Ag NPs were self-assembled into networks of one-dimensional chains in the presence of mercury(II) by chelation process; this causes an easily optical measurable change in the absorption spectrum of the particles in aqueous solution. © 2013 Springer Science+Business Media Dordrecht.
