product information:


Name: Manganese Oxide Nanoenzyme: MnO2, Mn3O4 NZs


Product performance: multi-enzyme activity, anti-oxidation function

Application field: With multi-enzyme activity: catalase-like, superoxide dismutase-like, glutathione peroxidase-like, with antioxidant function; its catalase-like activity can decompose tumor microenvironment H2O2 ultrasonic oxygen can solve the hypoxia problem of photodynamic therapy, sonodynamic therapy, and radiotherapy; its glutathione peroxidase activity can deplete the antioxidant glutathione GSH in the tumor microenvironment, thereby promoting The above-mentioned pro-oxidation treatment; after reacting with H2O2 and GSH, manganese oxide nanoenzyme degrades into Mn2+, which can promote the Fenton reaction, catalyze H2O2 to generate hydroxyl free radicals, and further promote oxidation and treatment of tumors. At the same time, the produced Mn2+ has the function of magnetic resonance imaging; Manganese oxide usually has strong near-infrared light absorption capacity and can be used for photothermal therapy and photoacoustic imaging; Mn3O4 has certain magnetic properties and can be used for magnetic resonance imaging; decomposition of H2O2 produces oxygen bubbles, which can be used for ultrasound imaging; it can also be used for composite loads Chemotherapeutics, gene drugs, etc. to achieve combined therapy
