• Preparation and encapsulation of CdTe QDs for bioimaging, Gordon Xu, Yian Zhu (PhD Student)

    Quantum dots (QD), such as CdTe, are found to be highly fluorescent, and are very promising imaging agents. However, the leaching of the toxic heavy metal ion and the liability to the oxidation in the physiological conditions limit the applications as the biomarker, therefore the goal of this project is to chemically protect QDs by coating them with silica (QDs@SiO2), in order to reduce the leaching of the heavy metal ions and the oxidation of Te. These coated QDs@SiO2 is then conjugated with some functional biospecies for target imaging.
