Description

technical field

[0001] The invention belongs to the technical field of nanomaterials, and in particular relates to a tumor-targeting photothermal agent, its preparation method and application. Background technique

[0002] Photothermal therapy is an emerging treatment method based on far-infrared waves generated by light-excited materials. With the development of photothermal reagents such as conjugated organic groups, carbon nanotubes, and gold nanorods, photothermal therapy has been widely used in tumor imaging and treatment. The specificity and selectivity of photothermal agents play a key role in the process of diagnosis and treatment. The geometric structure of nanomaterials has a great influence on their photothermal effect. In recent years, MoS with nanoscale thickness 2 , MoSe 2 , W 2 , WSe 2 Transition metal dichalcogenides have attracted extensive attention. Due to their unique physical and chemical properties, transition metal dichalcogenides have strong ap...
