Colorimetric and Label-Free Optical Detection of Pb<sup>2+</sup> Ions via Colloidal Gold Nanoparticles
The detection of the lead heavy metal (Pb) in water is crucial in many chemical processes, as it is associated with serious health hazards. Here, we report the selective and precise colorimetric detection of Pb<sup>2+</sup> ions in water, exploiting the aggregation and self-assembly mech...
