【Abstract】 With the advantages of strong near-infrared(NIR, 760～1700 nm) fluorescence emission, good biocompatibility, high photothermal conversion efficiency and good stability, the new indocyanine green IR-820 has stood out among the existing organic NIR fluorescent dyes and has been widely used in the research fields of biomedical imaging, fluorescent labeling, real-time cell monitoring and photothermal therapy. Researchers have modified IR-820 with different biochemical molecules to enhance its fluorescence and photothermal properties, multiple types of IR-820 fluorescent nanoparticles have been prepared and investigated in biomedical imaging and tumor photothermal therapy. This article has summarized the applications of the synthesized IR-820 nanoparticles in near-infrared fluorescence(NIRF) imaging and tumor photothermal therapy and synergistic therapy, aiming to provide a reference for the further development of NIR organic fluorescent dye IR-820 in the biomedical field and the further clinical translation.更多还原
