Abstract: In this paper we describe a simple colorimetric method for the sensitive and selective detection of Ba2+ ions, using 11-mercaptoundecylphosphonic acid functionalized gold nanoparticles (AuNPs–MPA) in aqueous solution. With increasing concentration, Ba2+ ions induced aggregation… read more here.
