A Highly Sensitive and Selective Colorimetric Hg(2+) Ion Probe Using Gold Nanoparticles Functionalized with Polyethyleneimine
A highly sensitive and selective colorimetric assay for the detection of Hg(2+) ions was developed using gold nanoparticles (AuNPs) conjugated with polyethyleneimine (PEI). The Hg(2+) ion coordinates with PEI, decreasing the interparticle distance and inducing aggregation. Time-of-flight secondary i...
