- Lanthanide carriers combine optical and magnetic properties to enable high-resolution, multiplexed, deep tissue imaging across near-infrared (NIR), X-ray, and magnetic resonance imaging (MRI) modalities.
- Lanthanide probes in the NIR-II window enable multiplexing encoded by distinct emission lifetimes, with centimeter-scale penetration and sub-10 µm resolution, advancing tumor detection, cerebrovascular thermography, and thermal monitoring of inflammation.
- Biosynthetic lanthanide-binding proteins provide high-relaxivity, targeted MRI, and favorable safety profiles, improving diagnostic performance.
- Lanthanide carriers could help define the next generation of biomedical imaging and fast-track the emerging field of theranostics—approaches that link diagnostic imaging with treatment selection, delivery, or monitoring.
- Senior author Prof Xiaogang Liu at the National University of Singapore stated that lanthanide carriers are expanding possibilities in biomedical imaging by delivering high-resolution, highly sensitive contrast across a wide range of imaging techniques.
- Lanthanide carriers are engineered chemical, nano-, or biomolecular systems that bind, incorporate, or stabilize lanthanide ions such as europium, terbium, and gadolinium.
- Research teams are increasingly developing lanthanide carriers as dual-function agents that combine imaging with targeted drug delivery, generating new opportunities for theranostic applications, including cancer and treatment.
- Dr. Yuxia Lui, First Author, National University of Singapore, mentioned that lanthanide carriers have already demonstrated truly compelling advantages across multiplexing, sensitivity, and functional imaging.

These carriers support long-term single particle tracking and subcellular thermometry, revealing nanoscale biophysical dynamics in living systems. Their use in the NIR-II window allows for centimeter-scale penetration and sub-10 µm resolution, crucial for advanced medical diagnostics.
According to Prof Xiaogang Liu from the National University of Singapore, "Lanthanide carriers are expanding possibilities in biomedical imaging by delivering high-resolution, highly sensitive contrast across a wide range of imaging techniques, from MRI and X-ray to optical imaging."5

The potential of these carriers extends to theranostics, linking diagnostic imaging with treatment selection and monitoring. Dr Jorge Méndez-Ramos from the University of La Laguna noted that lanthanides could lead to untapped applications in various technological fields, including healthcare.
Despite many advances remaining in the proof-of-concept stage, researchers emphasize that lanthanide carriers are positioned to bridge materials science, biophysics, and clinical needs, reshaping biomedical imaging toward more precise and personalized diagnostics.
