Optimizing the relaxivity of Gd(III) complexes appended to InP/ZnS quantum dots by linker tuning

Author affiliations

Abstract

Three bimodal MRI/optical nanosized contrast agents with high per-nanoparticle relaxivity (up to 2523 mM−1 s−1 at 35 MHz and 932 mM−1 s−1 at 200 MHz) have been prepared connecting up to 115 tris-aqua GdIII complexes to fluorescent non-toxic InP/ZnS quantum dots. The structure of the linker has an important effect on the relaxivity of the final multimeric contrast agent.
