This invention proposes a nanoaggregate based on a near-infrared II aggregation-induced emission (AIE) material, its preparation method, and its application, belonging to the field of medical technology. The nanoaggregate of this invention is self-assembled from an AIE material and an amphiphilic carrier material, a DSPE-PEG series polymer. This nanoaggregate exhibits AIE properties in the near-infrared II region and can downregulate the expression of heat shock protein 70 through a proteasome-dependent mechanism. In vitro and in vivo experiments show that this nanoaggregate can achieve complete tumor ablation under low-temperature photothermal therapy at 43-45℃ without the need for combined use with exogenous heat shock protein 70 inhibitors, while simultaneously achieving near-infrared II fluorescence imaging guidance. This invention has the advantages of being single-component, low-toxicity, and integrating imaging and therapy, and has broad application prospects in the field of low-temperature photothermal therapy for tumors.

This invention belongs to the field of medical device technology, and particularly relates to a tumor visualization ablation system and a tumor 3D model simulation method for using this system. Addressing the problem that existing technologies relying solely on image displays for real-time tumor ablation observation are susceptible to interference, this invention provides a tumor visualization ablation system and a tumor 3D model simulation method applied to this system. Based on a data model pre-stored in the main control module, this invention simulates the real-time ablation of the tumor by measuring temperature changes at different locations at varying distances from the tumor center during the ablation process. The simulation is then displayed in 3D on the control interface, allowing doctors to more accurately monitor the progress of tumor ablation.
