Description
Vyshakh Panakkal and co-authors (2024) synthesize MRI tracers that light up on fluorine scans, in a single step. Fluorine-19 MRI can image tracers with no background signal, since the body holds almost no fluorine, but the tracers must pack many fluorine atoms to be seen. The team built them from gradient copolymers, chains whose makeup shifts gradually along their length. These self-assemble into nanoparticles directly during synthesis, a one-pot process called gradient copolymerization-induced self-assembly.
One building block gives water-loving segments; the other carries the fluorine and forms the particle core. The particles came out spherical and gave exceptionally strong fluorine signals in relaxometry and imaging tests. They also proved non-toxic to pancreatic cancer cells in culture. A one-step route to sensitive tracers could simplify manufacturing for a kind of imaging that tracks cells and drugs without radiation.
