A novel trifunctional imaging probe containing a chelator of radiometal for PET, a NIR heptamethine cyanine dye, and a bioconjugatable handle, has been grafted onto AGuIX® nanoparticles a Michael addition reaction. The resulting functionalized nanoparticles have been fully characterized, radiolabelled with Cu, and evaluated in a mice TSA tumor model using multimodal (PET/MRI/optical) imaging.
