title: Functionalized fluorescent gold nanodots: synthesis and application for Pb2+ sensing.
abstract: We developed a novel strategy to prepare functionalized fluorescent gold nanodots (AuNDs) based on a ligand exchange reaction and demonstrated that glutathione modified AuNDs can be utilized for highly sensitive and selective Pb(2+) sensing in aqueous solution.
