Ultrasmall Biocompatible WO3-x Nanodots for Multi-Modality Imaging and Combined Therapy of Cancers

Ultrasmall biocompatible WO3-x nano-dots with an outstanding X-ray radiation sensitization effect are prepared, and demonstrated to be applicable for multi-modality tumor imaging through computed tomography and photoacoustic imaging (PAI), and effective cancer treatment combining both photothermal therapy and radiation therapy.
