In this study, magnetic multimodal nanoparticles with potential applications in magnetic- and nuclear-medicine imaging, magnetic resonance imaging, hyperthermia, and theranostic (therapeutic and diagnostic), applications were prepared by coating iron oxide nanoparticles with silica (core–shell), functionalizing with aminopropyltriethoxy silane and coupling with diethylenetriamine pentaacetic acid ligand (DTPA). Radiolabeling of core–shell–DTPA particles with 68Ga radiometal was carried out through chelation of 68Ga(III) ions by DTPA and was used for positron emission tomography. The biodistribution of the 68Ga-radiolabeled magnetic nanoparticles compared to free 68Ga(III) was checked in normal Balb/c mice up to 2 h.
