Graphical Abstract

A spatio-temporal feedback on the intratumoral catalytic Fenton reaction is described. It bridges dual-modal MRI/NIR imaging, thereby conquering inherent unpredictable barriers in chemodynamic therapy. This approach paves a way to accurately evaluate .OH dose-dependent feedback.

Abstract

Unpredictable in vivo therapeutic feedback of hydroxyl radical (.OH) efficiency is the major bottleneck of chemodynamic therapy. Herein, we describe novel Fenton-based nanotheranostics NQ-Cy@Fe&GOD for spatio-temporally reporting intratumor .OH-mediated treatment, which innovatively unites dual-channel near-infrared (NIR) fluorescence and magnetic resonance imaging (MRI) signals. Specifically, MRI signal traces the dose distribution of Fenton-based iron oxide nanoparticles (IONPs) with high-spatial resolution, meanwhile timely fluorescence signal quantifies .OH-mediated therapeutic response with high spatio-temporal resolution. NQ-Cy@Fe&GOD can successfully monitor the intracellular release of IONPs and .OH-induced NQO1 enzyme in living cells and tumor-bearing mice, which makes a breakthrough in conquering the inherent unpredictable obstacles on spatio-temporally reporting chemodynamic therapy, so as to manipulate dose-dependent therapeutic process.
