Current Progress and Future Perspectives on Metal- and Nonmetal-Doped Carbon Dots for Fluorescence, CT, and MRI Bioimaging
The demand for innovative biocompatible contrast agents suitable for multimodal imaging is rising, driven by the increasing incidence of cancer and chronic disease, the growing use of combined imaging workflows, and the safety limitations of conventional iodinated- and gadolinium-based agents. In this regard, carbon...
