N2 - This paper is devoted to the synthesis and application of CdTe quantum dot (QD) nanoparticles covered with organic ligands containing a thiol group, mostly mercaptopropionic acid (MPA) and glutathione (GSH). The simple one-step synthetic procedure was optimized to prepare greater quantities of nanoparticles for analytical purposes. The prepared CdTe QD nanoparticles were characterized by various analytical techniques, and their interaction with some metal ions (Cu(II), Pb(II), and Hg(II)) was studied by using luminescence spectroscopy in both steady-state and time-resolved modes. The mathematical analysis of the quenching effect of Cu(II) ions on the luminescence of CdTe QD nanoparticles shows that the static contribution is mostly responsible for the overall effect, but experimental conditions, such as pH, ionic strength, or the concentration of nanoparticles in aqueous solution, could also be important. The presence of metal ions in the form of a metal complex species could play an important role, and this phenomenon could be used to tune the selectivity of the quenching process. These findings have been utilized for the development of an analytical procedure for the detection and quantitative analysis of Cu(II) and Pb(II) ions in environmental water samples. In practice, this procedure could be easily implemented in a microplate format to increase throughput.
