| Abstract | High quality water-soluble semiconductor CdSe quantum dots (QDs) were prepared by a phase transfermethod, in which amphiphilic oligomers (polymaleic acid aliphatic alcohol ester) was used as surfacecoating agents. The as-prepared aqueous QDs were high fluorescent and extremely stable. Fourier trans-form infrared spectroscopy, thermogravimetric analysis, and transmission electron microscopy all indi-cated that the surfaces of the QDs were coated with amphiphilic oligomers. Alkyl chain length of theamphiphilic oligomers could dramatically affect the phase transfer efficiency. It was found that the useof polymaleic acid n-hexadecanol ester had the best result. A biocompatible test has been carried outand such prepared water-soluble QDs were used to target tumor cells and found that the oligomer-func-tionalized QDs were excellent fluorescence labels for detecting the human hepatoma cells. |
