Abstract

Several decades of research have identified the specific tumor microenvironment (TME) to develop promising nanotheranostics, such as pH-sensitive imaging, acidity-sensitive starving therapy, and hydrogen peroxide-activated chemotherapy, etc. Herein, a novel TME-mediated nanoplatform employing antiferromagnetic pyrite nanocubes is presented, exploiting the intratumoral, overproduced peroxide for self-enhanced magnetic resonance imaging (MRI) and photothermal therapy (PTT)/chemodynamic therapy (CDT). Through the activation of excessive peroxide in the tumor microenvironment, pyrite can lead to in situ surface oxidation and generate hydroxyl radicals to kill tumor cells (i.e., CDT). The increase of the valence…
