Label-Free Colorimetric Detection of Mercury (II) Ions Based on Gold Nanocatalysis

Label-Free Colorimetric Detection of Mercury (II) Ions Based on Gold Nanocatalysis

Herein, a label-free colorimetric nanosensor for Hg(II) is developed utilizing the hindering effect of Hg(II) on the kinetic aspect of gold nanoparticle (AuNPs) growth on the surface of gold nanostars (AuNSs). H-AuNS probes are synthesized and modified by 2-[4-(2-hydroxyethel) piperazine-1-yl] ethan...
