A Sub-Nanostructural Transformable Nanozyme for Tumor Photocatalytic Therapy
Highlights
An internal sub-nanostructural transformation of sub-nanostructural transformable gold@ceria (STGC-PEG) is initiated by the conversion between CeO2 and electron-rich state of CeO2−x, and active oxygen vacancies generation via the hot-electron injection from gold to ceria.
The sub-nanostructural transformation of STGC-PEG enhances the peroxidase-like activity and activates the plasmon-promoted oxidase-like activity, resulting in an augmented reactive oxygen species output.
STGC-PEG successfully achieves excellent low power (50 mW cm−2) near-infrared light-activated photocatalytic ablation of tumors in vivo.
期刊介绍:
Nano-Micro Letters is a peer-reviewed, international, interdisciplinary and open-access journal that focus on science, experiments, engineering, technologies and applications of nano- or microscale structure and system in physics, chemistry, biology, material science, pharmacy and their expanding interfaces with at least one dimension ranging from a few sub-nanometers to a few hundreds of micrometers. Especially, emphasize the bottom-up approach in the length scale from nano to micro since the key for nanotechnology to reach industrial applications is to assemble, to modify, and to control nanostructure in micro scale. The aim is to provide a publishing platform crossing the boundaries, from nano to micro, and from science to technologies.
