(PhysOrg.com) -- Radioactively labeled compounds are important for use as imaging probes or radiotherapeutic agents. Most radioisotopes with suitable decay properties are transition metals or elements with metallic character. Therefore, bifunctional chelators are required for stable tethering of a given radionuclide to targeted biomolecules. However, preparing such multifunctional radioconjugates by conventional synthetic means is a significant challenge.
