Novel cellulose polyampholyte-gold nanoparticle-based colorimetric competition assay for the detection of cysteine and mercury(II)
We provide a highly sensitive and selective assay to detect cysteine (Cys) and Hg(2+) in aqueous solutions using Au nanoparticles (NPs) stabilized by carboxylethyl quaternized cellulose (CEQC). This method is based on the thiophilicity of Hg(2+) and Au NPs as well as the unique optical properties of...
