Abstract：

As a redox active layered transition metal dioxide nanomaterial, manganese dioxide (MnO₂) nanosheets have been widely used in the field of biosensing and biomedicine in recent years because of its advantages of large surface area , strong optical absorption and oxidation capacity, high catalytic activity and good mechanical properties. This paper briefly summarizes the nanostructure and properties of MnO₂ nanosheets, presents in detail their applications in biosensing, biological imaging, drug delivery and cancer treatment, and finally looks forward to the future development prospects and challenges of MnO₂ nanosheets.
