Macrocyclic chelators have been widely employed in the realm of nanoparticle‐based positron emission tomography (PET) imaging, whereas its accuracy remains questionable. Here, we found that 64Cu can be intrinsically labeled onto nanographene based on interactions between Cu and the π electrons of graphene without the need of chelator conjugation, providing a promising alternative radiolabeling approach...
Alte Technik, neue Anwendung: Eine einfache und effiziente chelatfreie Methode zur Synthese eines neuen difunktionellen PET/MRI‐Reagens wurde entwickelt. Die Markierung der Oberfläche von superparamagnetischen Eisenoxid‐Nanopartikeln (SPIONs) mit Radioarsen (*AsIII und *AsV, *=71, 72, 74, 76) führte zu *As‐SPIONs, die zur simultanen PET/MRI‐Bildgebung zur Krebsdiagnose, Lymphknotenabbildung und möglicherweise...
