Abstract Background: Excellent imaging performance and good biocompatibility of contrast agents are considered as prerequisites for accurate tumor diagnosis and treatment. Results: Herein, a novel imaging nanoprobe with actively targeting performance based on ultrasmall paramagnetic iron oxide (USPIO) was constructed by a facile cation exchange strategy followed by conjugation with transferrin (Tf). The stable gadolinium (Gd3+) chelation endows the nanoparticles (NPs) with a low value of r2/r1 (1.28) and relatively high r1 value of 3.2 mM-1s-1, enabling their use in T1-weighted positive MR imaging.Conclusion: This constructed transferrin modified gadolinium-iron chelate nanoprobe, named as TUG, shows high biocompatibility within a given dose range. More importantly, compared with clinically used Gd-based small molecule contrast agents, the obtained TUG can be more engulfed by breast cancer cells, showing much enhanced T1-weighted positive MR imaging in either subcutaneous or in situ tumor models of breast cancer. This novel nanoprobe holds enormous promise to be utilized as a targeting contrast agent with high efficacy for T1-weighted positive MR imaging.
