摘要

A simple, cost-effective yet rapid and sensitive colorimetric sensor for the detection of Hg2+ using L-cysteine functionalized gold nanoparticles induced by ultraviolet radiation was developed. The sensitivity and selectivity of detection was also investigated. The L-cysteine modified gold nanoparticles can be induced to aggregate quickly in the presence of Hg2+, especially with the assistance of ultraviolet radiation. The presence of Hg2+ can be monitored by the colorimetric response of gold nanoparticles. The detection of Hg2+ could be realized, after measuring the UV-vis spectra, with a detection limit of 100 nM. The selectivity of this method has been investigated by other divalent metal ions. The effective colorimetric sensor can be used for on-site and real-time Hg2+ detection.
