Biocompatible TeSex nano-alloys for PT/PA/CT/PET imaging-guided NIR-II-photothermal therapy

Photothermal nanotheranostics, especially in the NIR-II region, exhibits a great potential in precision and personalized medicine, owing to high tissue penetration of NIR-II light. The development of NIR-II-photothermal theranostic nanoplatforms with high biocompatibility and photothermal efficiency are urgently needed. In this work, researchers propose a nano-alloying strategy to dop Se into Te nanostructure for eliminating inherent cytotoxicity and enhancing biocompatibility, developing TeSex nano-alloys as a versatile theranostic nanoplatform.
