The kinetic inertness profile of Cu(ii) complexes of TRAP-conjugates enables simple Cu(ii) removal after click functionalisation and confirms their suitability for Cu-64-PET.
comparison of data for trimer/monomer pairs of NT ligands and other targeting vectors (peptides and peptoids targeting integrins αvβ3, α5β1, and αvβ6, the PSMA-ligand DUPA (2-[3-(1,3-dicarboxypropyl)-ureido]pentanedioic acid), and nitroimidazoles targeting hypoxia) revealed that multimers always exhibit higher target affinities and tumor uptake, but not necessarily improved tumor-to-tissue ratios.

TRAP, a Powerful and Versatile Framework for Gallium-68 Radiopharmaceuticals
A veritable gallium TRAP: Triazacyclononane‐phosphinic acid chelators (TRAP) form highly stable complexes with Ga3+ (see figure) extremely efficiently over a wide pH range. Homo‐ and heteromultimeric bioconjugates can be synthesized in a straightforward manner, all of which renders TRAP a chelator with ideal properties for 68Ga positron emission tomography (PET) imaging agent elaboration.
