Abstract:

Due to the distinct advantages of deep tissue penetration and high spatial-temporal resolution, near- infrared-Ⅱ(NIR-Ⅱ, 1000—1700 nm) fluorescence imaging technology that developed rapidly in the last decade has attracted extensive attentions for its great potential in tumor diagnosis and therapy. In this review, we first illustrated the mechanism and advantages of fluorescence imaging in the NIR-Ⅱ window. Afterward, the current fluorophores were categorized according to chemical structures, and their properties were introduced respectively. We also highlighted the advances in the development of fluorescence probes and their applications in tumor detection, surgery resection and phototherapy. Finally, we discussed the limitations of current NIR-Ⅱ fluorescence probes and the challenges during clinical translation as well as prospects for future biomedical applications.

Key words: Near-infrared-Ⅱ, Fluorescence imaging, In vivo imaging, Drug delivery, Tumor diagnosis and therapy
