Biodegradable flower-like manganese for synergistic photothermal and photodynamic therapy applications

A flower-like nanostructured MnO 2 with near-infrared (NIR) light-triggered high photothermal conversion capability of 30% and reactive oxygen species (ROS) generation ability was successfully developed. Different from the reported MnO 2 nanomaterials those were used in the nanomedicine field for only relieving tumor hypoxia and/or imaging, the flower-like MnO 2 inherently acts as a competent agent for simultaneously enhanced photothermal and photodynamic therapy.
