Singlet-oxygen-sensitizing near-infrared-fluorescent multimodal nanoparticles.
Nanoprobes based on quantum clusters (QC) with near-infrared fluorescence, magnetic-resonance-imaging contrast, and singlet-oxygen-sensitized intracellular fluorescence are studied. The generation of singlet oxygen and singlet-oxygen-sensitized fluorescence uncaging by magnetic and NIR-emitting nanoparticles are exploited for multimodal bioimaging in vitro.
