Core–multi-shell design: unlocking multimodal capabilities in lanthanide-based nanoparticles as upconverting, T₂-weighted MRI and CT probes

Abstract

Core/shell/shell nanoparticle design with a controlled inner NaGdF4 layer between the upconverting Er/Yb-doped NaGdF4 core and the magnetic NaDyF4 shell suppressed Dy3+-induced emission loss, while simultaneously enhancing MRI T2 and CT performance.

Lanthanide-based nanomaterials for temperature sensing in the near-infrared spectral region: illuminating progress and challenges

“…In addition, the UC emission that is often observed in parallel to NIR emission or the magnetic properties of Ln 3+ ions such as Gd 3+ and Dy 3+ bring multifunctionality to the scene, allowing for theranostics or multimodal imaging in addition to thermal sensing. 123,124…”

Hourglass-Shaped Homo- and Heteronuclear Nonanuclear Lanthanide Clusters: Structures, Magnetism, Photoluminescence, and Theoretical Analysis

“…Lanthanide (Ln) molecular complexes have gained significant interest across a wide range of disciplines, which include catalysis, magnetic resonance imaging, luminescent materials, multimodal imaging probes, single-molecule magnets (SMMs), − and quantum information processing (QIP) . Over the last few decades, numerous Ln-based clusters have been reported, with nuclearities such as Ln 3 , Ln 4 , , Ln 5 , − Ln 6 , Ln 8 , Ln 9 , ,, Ln 10 , Ln 12 , Ln 16 , Ln 19 , Ln 36 , Ln 48 , , Ln 104 , etc.…”

Hexanuclear {ZnII4FeIII2} and {ZnII4CrIII2} complexes from the use of potentially tetradentate NOO′O′′ Schiff-base ligands

“…The field of mixed-metal, atom- or ion-based materials is receiving 1–3 great attention of researchers working in solid-state chemistry and condensed-matter physics, for example in the area of multiferroics. 2 Molecular inorganic chemists are also interested in synthesizing and characterizing mixed-metal compounds.…”
