Abstract

In view of the significance and urgency of the speciation analysis of quantum dots (QDs) and their degradation products for clarifying their degradation rules and toxicity mechanisms, a method for the identification and quantification of CdTe QDs and corresponding ionic species in complex matrices was developed using capillary zone electrophoresis (CZE) coupled to inductively coupled plasma-mass spectrometry (ICP-MS). The quality assessment of commercial CdTe QDs and serum pharmacokinetics of synthesized CdTe QDs in rats were successfully undertaken using the developed CZE-ICP-MS method.
