Two are better than one: Multivalent scaffolds for targeted PET imaging probes not only feature chelators that form stable and neutral complexes with a radiometal but also contain functional groups for presentation of multiple targeting molecules. A bivalent scaffold was synthesized and coupled with a targeting ligand to afford the probe, which was used to efficiently image tumors in vivo (see picture).
