Colorimetric response to mercury-induced abstraction of triethylene glycol ligands from a gold nanoparticle surface

Wednesday, July 23, 2008 --- 78 days ago

http://xlink.rsc.org/?DOI=b808433e&RSS=1

A gold nanoparticle supported by triethylene glycol ligands has been demonstrated to act as a specific colorimetric sensor for aqueous mercury(ii) ion. In this process, ligand abstraction from the gold surface by the mercury ion occurs prior to the color change. ...
