functionalizing nanoparticles and directly quantifyingconjugation efficiency and ligandsurfacedensity has been developed. Attachment of 3‐azido‐modifed RGD‐peptides to PEGylated liposomes was achieved by using Cu‐free click conditions. Upon coupling a fluorophore is formed, which could be utilized to monitor conjugation efficiency and the obtained ligandsurfacedensity in situ, without prior purification

Attachment of DOTA to a novel monofluoro-cyclooctyne facilitates bioconjugation to an azide-modified peptide via Cu-free clickchemistry. The resulting conjugate was radiolabeled with 111In to afford a potential targeted molecular imaging agent with high specific activity and an excellent radiochemical purity.

A strain-induced copper-free click reaction mediated by a new and easily prepared cyclooctyne derivative was used to efficiently assemble a DOTA biotin adduct capable of radionuclide ((68)Ga) uptake. This synthetic strategy offers a potentially general and convenient means of preparing targeted radiolabeling and radiotherapeutic agents.
