A near-infrared dual-channel fluorescent probe for ultrasensitive detection of Zn<sup>2+</sup> and Cd<sup>2+</sup> in food safety and bioimaging applications.
uptake in 4T1 cells. In vivo experiments demonstrate its ability to track metal ion dynamics in tumor-bearing mouse models. Compared to existing methods, this probe integrates near-infrared emission, high sensitivity, and a large Stokes shift, allowing it to effectively address complex practical application requirements. However, further validation and field-level evaluation are still required for routine deployment.
