摘要：

Multimodal probes of Gd-III-functionalized silica-coated CdS:Mn/ZnS quantum dots (see figure) that exhibit yellow fluorescence and strong paramagnetism are reported. High magnetic resonance imaging (MRI) contrast is exhibited by these quantum dots. These properties make for a probe that can operate in multiple modes, which is highly desirable for in vivo bioimaging applications.
