摘要：

(Figure Presented) Bifunctional nanocomposites comprising semiconductor and magnetic nanoparticles are of interest in biological applications for biolabeling, bioimaging, and cell separation. To this end, a nanocomposite system that consists of Fe2O3 magnetic nanoparticles and CdSe quantum dots and which exhibits superparamagnetism and tunable emission properties was prepared and used to label different live cell membranes (see picture). © 2007 Wiley-VCH Verlag GmbH & Co.
