Recently, the Bismuth Science and Health Medicine Materials Team of School of Materials and Chemistry published a review article titled "Recent advances in functionalized bismuth chalcogenide nanomaterials: cancer theranostics, antibacterial and biosensing" in Coordination Chemistry Reviews (CAS I, IF: 24.833), the top international journal of chemistry. The review article titled "Recent advances in functional bismuth chalcogenide nanomaterials: Cancer theranostics, antibacterial and biosensing. D. student Xi Wang was the first author of the paper, and Associate Professor Yuhao Li and Professor Yuqing Miao were the co-corresponding authors.

In modern society, the incidence of cancer and bacterial infectious diseases is on the rise, and the main clinical treatments for these diseases are surgery, chemotherapy and radiotherapy, but all these methods have certain limitations. With the continuous development of nanotechnology, nanomaterials have attracted widespread attention for their good biocompatibility and excellent physicochemical properties. Oxybismuth-based nanomaterials (Bi2X3, X= O, S, Se, Te) are an important class of bismuth-based nanomaterials. These materials are characterized by low cost, high stability, controllable shape and size, strong X-ray attenuation coefficient and near-infrared absorption, unique photothermal conversion efficiency, good catalytic activity, etc. They also have unique structures and tunable physicochemical properties, including optical absorption range and band gap. These properties not only make the oxygenated bismuth-based nanomaterials promising for combined tumor therapy, multimodal imaging, antibacterial and biosensing applications, but also provide new ideas for clinical applications. Therefore, a systematic review of this type of material is of great significance.
