Uptake of water soluble CdTe quantum dots in living cells of euglena gracilis

Water-soluble CdTe quantum dots (QD600) were synthesized by hydrothermal route. The uptake of QD600 in living cells of euglena gracilis was studied. The luminescence spectra show that the QD600 were bound in cells after incubation. The fluorescence images, measured by confocal laser scanning microsc
