Simultaneous Fenton‐like Ion Delivery and Glutathione Depletion by MnO₂‐Based Nanoagent to Enhance Chemodynamic Therapy

Chemodynamic therapy (CDT) utilizes iron‐initiated Fenton chemistry to destroy tumor cells by converting endogenous H 2 O 2 into the highly toxic hydroxyl radical ( . OH). There is a paucity of Fenton‐like metal‐based CDT agents. Intracellular glutathione (GSH) with . OH scavenging ability greatly reduces CDT efficacy. A self‐reinforcing CDT nanoagent based on MnO 2 is reported that has both Fenton‐like Mn 2+ delivery and GSH depletion...
