Sensitive Colorimetric Hg(2+) Detection via Amalgamation-Mediated Shape Transition of Gold Nanostars

Reliable and sensitive methods to monitor mercury levels in real samples are highly important for environment protection and human health. Herein, a label-free colorimetric sensor for Hg(2+) quantitation using gold nanostar (GNS) has been demonstrated, based on the formation of Au-Hg amalgamate that...
