Abstract
In recent years, manganese dioxide (MnO2) nanoparticles with unique physicochemical properties have been widely used in many biomedical fields, such as biosensors, contrast agents, tumor therapy, and drug delivery. From these applications, MnO2 nanoparticles have great clinical translation potential. However, by contrast, the in vitro and in vivo biosafety of MnO2 nanoparticles have been deeply and thoroughly clarified for the clinical translation, which hinders their clinical applications. In this work, we deeply investigated the blood safety of MnO2 nanoparticles by conducting a series of in vitro and in vivo experiments. These included the effects of MnO2 nanoparticles on morphology of red blood cells, activation of platelets, coagulation functions, and toxicity of key organs. The obtained results show that these effects displayed a concentration-dependent manner of MnO2 nanoparticles. Different safe concentration ranges could be found in the different experimental index. This study provides important guidance for the specific biomedical applications of MnO2 nanoparticles, greatly accelerating their laboratory development and clinical translation.
