Selective Binding and Light-Driven Release of Fluorous PF6– and Radioactive 99TcO4– Anions for All-to-Nothing Liquid–Liquid Extraction

The purity of fresh water supplies fit for human, agriculture, and industrial sectors is evolving into a leading global priority. Separation of ionic analytes from water using liquid-liquid extraction is one strategy for high selectivity and large throughput volumes. However, it remains a challenge to selectively extract target ions, like the radioactive pertechnetate (99T…

Development of 225Ac-doped biocompatible nanoparticles for targeted alpha therapy

Targeted alpha therapy (TAT) relies on chemical affinity or active targeting using radioimmunoconjugates as strategies to deliver α-emitting radionuclides to cancerous tissue. These strategies can be affected by transmetalation of the parent radionuclide by competing ions in vivo and the bond-breaking recoil energy of decay daughters. The retention of α-emitting radionucli…

Tetradentate Ligand’s Chameleon-Like Behavior Offers Recognition of Specific Lanthanides

The surging demand for high-purity individual lanthanides necessitates the development of novel and exceptionally selective separation strategies. At the heart of these separation systems is an organic compound that, based on its structural features, selectively recognizes the lighter or heavier lanthanides in the trivalent lanthanide (Ln) series. This work emphasizes the…
