摘要：

Highly photoluminescent gold nanodots (Au NDs) via etching and co-deposition of hybridized ligands [11-mercaptoundecanol (11-MU) and its complexes with amphiphilic ligands] on gold nanoparticles (similar to 3 nm) have been prepared and employed for the detection of nitrite based on the analyte-induced photoluminescence quenching.
