 Chow2 adiox at ZiF67 is a novel nanomedicine designed to deliver oxygen and hydrogen peroxide to cancer cells for enhanced chemo slash chemodynamic therapy. It works by breaking down in the acidic environment of tumors, releasing the fentanyl catalyst Code II Plus and the chemotherapy drug Doxorubicin, DOX, which are then able to penetrate deeper into the tumor. Once inside the tumor, the Code II Plus reacts with water to create hydrogen peroxide, which can then be used to oxidize the Code II Plus to form more toxic hydroxyl radicals. This combination of treatments has been shown to be effective at killing cancer cells while minimizing damage to healthy tissue. This article was authored by Xudao Gao, Yin Jin, Kuan Gu, and others.
