The mercury prize : A highly selective and sensitive unmodified gold‐nanoparticle (AuNP)‐based colorimetric sensor for Hg 2+ ions in aqueous media uses the Hg 2+ ‐promoted desulfurization reaction of a thiourea derivative and the reactivity of a thiourea derivative to gold nanoparticles. This sensor also allows a quantitative assay of the analyte in a neutral aqueous solution, down to a concentration of 10 −7 M .
