Comparative study of core- and surface-radiolabeling strategies for the assembly of iron oxide nanoparticle-based theranostic nanocomposites

Abstract

This work highlights the superiority of the surface-radiolabeling strategy over the core-labeling strategy in the assembly of radioactive iron oxide nanoparticle (IONP)-based nanocomposites for use in multimodal imaging and targeted therapy. It also implies a possible overestimation of the labeling stability in previous studies and points out directions for further optimization.
