Ag 2 S quantum dot-based magnetic resonance/fluorescence dual-mode imaging nanoprobes for tumor diagnosis

This is the authors' abstract. We don't add key points for this paper.

S quantum dots (QDs) for NIR fluorescence imaging. Additionally, the probe conjugated the MRI contrast agent Gd-DOTA and cetuximab, which targeted EGFR on the tumor cell membrane surface, to achieve dual-modal imaging in the tumor area. This strategy provided a methodology for the accurate diagnosis of early-stage tumor lesions and guides precise lesion resection during surgery, offering significant potential for clinical application.
