Anti-VEGF antibody conjugated CdHgTe quantum dots as a fluorescent probe for imaging in living mouse

The dual-function anti-VEGF antibody conjugated CdHgTe quantum dots with good targeting property was successfully prepared. In this system, anti-VEGF antibody is not only a target agent but also a therapeutic drug. The anti-VEGF antibody conjugated near-infrared quantum dots can achieve the purposes of detection and treatment at the same time. As-prepared dual-function fluorescent probe in this work has been successfully applied for in vivo and in vitro imaging, which is promising in rapid tumor detection.
