Abstract
Multifunctional nanoplatform draws increasing attention due to its appealing structural and functional features. In this paper, magnetic CuInS2–ZnS nanocomposites (MCZN) were prepared by integrating silica (SiO2)-encapsulated magnetite (Fe3O4) nanocrystals with 3-mercaptopropanoic acid (MPA)-modified CuInS2–ZnS quantum dots (QD). The obtained MCZN, with an average size of about 50nm, exhibited both fluorescent and superparamagnetic properties. Confocal laser scanning microscopic observation confirmed that these MCZN could enter cancer cells and successfully image the cells. These properties opened up possibilities for the wide applications of MCZN in multimodal diagnosis and cancer treatments.
