Toxicity and Oxidative Stress Biomarkers in the Organs of Mice Treated with Mesoporous Polydopamine Nanoparticles Modified with Iron and Coated with Cancer Cell Membrane.

Purpose: Polydopamine nanoparticles (PDA NPs) have great potential in medicine. Their applications being widely investigated in cancer therapy, imaging, chemotherapy, photodynamic therapy (PDT), photothermal therapy (PTT), and tissue repair. The aim of our study was to assess the in vivo toxicity and changes in oxidative stress biomarkers in organs of animals treated with mesoporous PDA NPs modified with iron (MPDAFe NPs), coated with the cancer cell membrane and loaded with doxorubicin (DOX), and subsequently subjected to PTT.
