Abstract

A colorimetric detection system for Hg²⁺ in aqueous media is developed with high selectivity and sensitivity based on the mixing of gold nanoparticles and oligopeptides. Oligopeptides with cysteine (Cys) at both ends normally aggregate gold nanoparticles, which can be disturbed by Hg²⁺ through formation of an oligopeptide-Hg²⁺ complex. © 2011 Wiley-VCH Verlag GmbH & Co.
