On-site, rapid and visual method for nanomolar Hg(2+) detection based on the thymine–Hg(2+)–thymine triggered “double” aggregation of Au nanoparticles enhancing the Tyndall effect

This work describes a new nanosensor for the simple, rapid, portable, colorimetric analysis of mercury(ii) (Hg(2+)) ions by combining the sensitive Tyndall effect (TE) of colloidal Au nanoparticles (AuNPs) with specific thymine–Hg(2+)–thymine (T–Hg(2+)–T) coordination chemistry for the first time. F...
