In this paper, we systematically investigated the interaction between CdTe QDs and thiol- polyethylene glycol (PEG-SH) using capillary electrophoresis (CE) and fluorescence spectrometry. We found that PEG-SH was able to bind to CdTe QDs and form QDs-PEG-SH conjugates. The QDs-PEG-SH conjugates were well separated from QDs and PEG-SH reaction mixture by CE. The data demonstrated that PEG-SH possessed strong adsorption to QDs, and QDs-PEG-SH conjugates had showed good stability and fluorescent property, and had potential applications in biological and biomedical fields. Moreover, it also illustrated that CE was a useful tool to study the interaction of QDs with ligand molecules.
